The `number_format` filter has been included in the Twig core since the end of December 2011. The relevant commit is [here][1].

Usage: `number_format(decimals, decimalSeparator, thousandSeparator)`

    {{ total|number_format(2) }}
    {{ total|number_format(0, &#39;.&#39;) }}
    {{ total|number_format(2, &#39;.&#39;, &#39;,&#39;) }}

Read more about it in the [docs][2]

The [Twig Extensions library][1] contains a number of useful extensions for Twig. With the release of version 1.2.0, a [`localizedcurrency` filter][2] has been added to the Intl extension. As the name suggests, this filter will format a number based on the current locale. It uses PHP&#39;s [`NumberFormatter`][3] class to do so.

Usage
-----

This filter is very easy to use. The only required argument for the filter is the 3-letter [ISO 4217][4] currency code. For instance, to display an amount of 27.99 in Euros, use the following line of code:

    {{ price|localizedcurrency(&#39;EUR&#39;) }}

This will display different results depending on the locale:

 - `€27.99` if the locale is set to `en`
 - `27,99 €` if the locale is set to `fr`
 - `€ 27,99` if the locale is set to `nl`


## Installation / setting the locale ##

Installation instructions for the Intl extension can be found in [this seperate answer][5].

If you are using an older version of twig and you don&#39;t want to install any extensions you can use the format filter like this:

    {{ &quot;%.2f&quot;|format(total) }}

Not very nice, but it works.

Basically `format` works like [PHP&#39;s `sprintf` function][1]

Use the `format_currency`

From version 2.12 `format_currency` filter was added. More information in the official documentation https://twig.symfony.com/doc/2.x/filters/format_currency.html

In Objective C I&#39;ve been using the following code to hash a string:

    -(NSString *) sha1:(NSString*)stringToHash {	
        const char *cStr = [stringToHash UTF8String];
        unsigned char result[20];
        CC_SHA1( cStr, strlen(cStr), result );
        return [NSString stringWithFormat:@&quot;%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X%02X&quot;,
			result[0], result[1], result[2], result[3], 
			result[4], result[5], result[6], result[7],
			result[8], result[9], result[10], result[11],
			result[12], result[13], result[14], result[15],
			result[16], result[17], result[18], result[19]
			];	
    }

Now I need the same for Android but can&#39;t find out how to do it. I&#39;ve been looking for example at this: https://stackoverflow.com/questions/5757024/make-sha1-encryption-on-android
 but that doesn&#39;t give me the same result as on iPhone. Can anyone point me in the right direction?

How to SHA1 hash a string in Android?

I&#39;m developing android with SDK 2.3.3 using Eclipse IDE.
As you all know to run my app, I should generate virtual device.
From &#39;create new AVD&#39; window, I can see many targets. 
There are 2 targets for API level 10 such as &#39;android 2.3.3&#39; and Google APIs(Google Inc).
Among those targets, I&#39;m uncertain which one I should choose.

My question is what&#39;s the difference between them.

Thanks in advance

I have seen that some browsers localize the `input type=&quot;number&quot;` notation of numbers. 

So now, in fields where my application displays longitude and latitude coordinates, I get stuff like &quot;51,983&quot; where it should be &quot;51.982559&quot;. My workaround is to use `input type=&quot;text&quot;` instead, but I&#39;d like to use the number input with correct display of decimals.

Is there a way to **force browsers to use a decimal point** in the number input, regardless of client-side local settings?

(It goes without saying that in my application I anyway correct this on the server side, but in my setup I also need it to be correct on the client side (because of some JavaScript)).

Thanks in advance.

***UPDATE***
As of right now, checking in Chrome Version 28.0.1500.71 m on Windows 7, the number input just does not accept decimals formatted with a comma. Proposed suggestions with the `step`attribute do not seem to work.

Force decimal point instead of comma in HTML5 number input (client-side)

Is there a way to force the number keyboard to come up on the phone for an `&lt;input type=&quot;text&quot;&gt;`? I just realized that [`&lt;input type=&quot;number&quot;&gt;`](http://www.w3.org/TR/html-markup/input.number.html) in HTML5 is for “floating-point numbers”, so it isn’t suitable for credit card numbers, ZIP codes, etc.

I want to emulate the numeric-keyboard functionality of `&lt;input type=&quot;number&quot;&gt;`, for inputs that take numeric values other than floating-point numbers. Is there, perhaps, another appropriate `input` type that does that?

Phone: numeric keyboard for text input

I decided to create simple *isEven* and *isOdd* function with a very simple algorithm:

    function isEven(n) {
      n = Number(n);
      return n === 0 || !!(n &amp;&amp; !(n%2));
    }

    function isOdd(n) {
      return isEven(Number(n) + 1);
    }

That is OK if n is with certain parameters, but fails for many scenarios. So I set out to create robust functions that deliver correct results for as many scenarios as I could, so that only integers within the limits of javascript numbers are tested, everything else returns false (including + and - infinity). Note that zero is even.


    // Returns true if:
    //
    //    n is an integer that is evenly divisible by 2
    //
    // Zero (+/-0) is even
    // Returns false if n is not an integer, not even or NaN
    // Guard against empty string
    
    (function (global) {
      
      function basicTests(n) {
      
        // Deal with empty string
        if (n === &#39;&#39;) 
          return false;
      
        // Convert n to Number (may set to NaN)
        n = Number(n);
      
        // Deal with NaN
        if (isNaN(n)) 
          return false;
      
        // Deal with infinity - 
        if (n === Number.NEGATIVE_INFINITY || n === Number.POSITIVE_INFINITY)
          return false;
      
        // Return n as a number
        return n;
      }
      
      function isEven(n) {
      
        // Do basic tests
        if (basicTests(n) === false)
          return false;
      
        // Convert to Number and proceed
        n = Number(n);
      
        // Return true/false
        return n === 0 || !!(n &amp;&amp; !(n%2));
      }
      global.isEven = isEven;
      
      // Returns true if n is an integer and (n+1) is even
      // Returns false if n is not an integer or (n+1) is not even
      // Empty string evaluates to zero so returns false (zero is even)
      function isOdd(n) {
    
        // Do basic tests
        if (basicTests(n) === false)
          return false;
    
        // Return true/false
        return n === 0 || !!(n &amp;&amp; (n%2));
      }
      global.isOdd = isOdd;
    
    }(this));

Can anyone see any issues with the above? Is there a better (i.e. more accurate, faster or more concise without being obfuscated) version?

There are various posts relating to other languages, but I can&#39;t seem to find a definitive version for ECMAScript.

Testing whether a value is odd or even

    #define SIZE 9
    int number=5;
    char letters[SIZE]; /* this wont be null-terminated */
    ... 

    char fmt_string[20];
    sprintf(fmt_string, &quot;%%d %%%ds&quot;, SIZE);
    /* fmt_string = &quot;%d %9d&quot;... or it should be */

    printf(fmt_string, number, letters);

Is there a better way to do this?

So all I want is to get rid of the -0600 timezone offset. How can I do this? Thanks.

Maybe this is a silly question, but I cannot guess how to solve it if it&#39;s not creating a method. Maybe there&#39;s a &quot;natural way&quot; to do it, like in C for example. Here&#39;s the problem:

I have a var:

    double a;

And I want to show it only with 2 or 3 decimals. When I try to show it:

    Text.setText(&quot;Value of a: &quot; + String.valueOf(a));

It gives something like:

&gt; Value of a: 5.234966145

And i would want just

&gt; Value of a: 5.23

Without changing the real value of a so it shows the approximate number but works with the real number.

I have a Symfony2 Twig template. I want to output the value of a config parameter in this twig template (a version number). Therefore I defined the config parameter like this:

    parameters:
        app.version: 0.1.0

I&#39;m able to use this config parameter in Controllers but I have no clue how to get it in my Twig template. 

How to get config parameters in Symfony2 Twig Templates

I have a multidimensional array where some objects exist and others don&#39;t. I keep getting a

**Method &quot;code&quot; for object &quot;stdClass&quot; does not exist in...**?

The code I am using in my template is:

    {% for item in items %}
        &lt;p&gt;{% if item.product.code %}{{ item.product.code }}{% endif %}&lt;/p&gt;
    {% endfor %}

Some products do not have this code and unfortunately this data structure is provided via a feed, so I cannot change it.

When I looked at the Twig documentation I interpreted that if an object or method was not there it would just return null?

How do you check if an object exists in the Twig templating engine in Symfony2?

View layer pattern where you only present what you have been given is fine and all, but how do you know what is available? Is there a &quot;list all defined variables&quot; functionality in TWIG? *Is there a way to dump a variable?*

The solution I found by searching for it was to define a function where I can use my [existing php debug tools][1] by [injecting a function][2], but all references I have found to that includes these nice two lines of code, but nowhere is it specified where to place them. Going by the fact that they need a **$loader** variable defined, I tried /app/config/autoload.php but the $loader there was the wrong kind. *Where do I place the php code for adding a twig function?*

How to var_dump variables in twig templates?

I am using [Twig][1] as templating engine and I am really loving it. However, now I have run in a situation which definitely mustbe accomplishable in a simpler way than I have found.

What I have right now is this:

    {% for myVar in someArray %}    
        {% set found = 0 %}
	    {% for id, data in someOtherArray %}
		    {% if id == myVar %}
			    {{ myVar }} exists within someOtherArray.
			    {% set found = 1 %} 
		    {% endif %}
	    {% endfor %}

	    {% if found == 0 %}
			{{ myVar }} doesn&#39;t exist within someOtherArray.
	    {% endif %}
    {% endfor %}


What I am looking for is something more like this:

    {% for myVar in someArray %}    
	    {% if myVar is in_array(array_keys(someOtherArray)) %}
           {{ myVar }} exists within someOtherArray.
        {% else %}
           {{ myVar }} doesn&#39;t exist within someOtherArray.
        {% endif %}
    {% endfor %}

Is there a way to accomplish this which I haven&#39;t seen yet?

If I need to create my own extension, how can I access myVar within the test function?

Thanks for your help!

I&#39;m using FOSuserbundle to get started with User registration https://github.com/FriendsOfSymfony/FOSUserBundle

I&#39;ve got it registering / logging in and out. What I want to do now is grab the logged in users data and present it on every page of my site. Like &quot;Hi username&quot; in the header type of thing.

It seems like embedding a controller in my **app/Resources/views/base.html.twig** is the best way to do this http://symfony.com/doc/current/book/templating.html#embedding-controllers

So I wrote my controller to access the user profile data. What I can&#39;t figure out is how to access FOS methods in my embedded controller. So from my **Acme/UserBundle/Controller/UserController.php** I want to do this:



    public function showAction()
    {
        $user = $this-&gt;container-&gt;get(&#39;security.context&#39;)-&gt;getToken()-&gt;getUser();
        if (!is_object($user) || !$user instanceof UserInterface) {
            throw new AccessDeniedException(
                   &#39;This user does not have access to this section.&#39;);
        }
    
        return $this-&gt;container-&gt;get(&#39;templating&#39;)
          -&gt;renderResponse(&#39;FOSUserBundle:Profile:show.html.&#39;.$this-&gt;container
          -&gt;getParameter(&#39;fos_user.template.engine&#39;), array(&#39;user&#39; =&gt; $user));
    }


which I grabbed from:
