I believe it&#39;s in `&lt;float.h&gt;`: `FLT_MAX`, `DBL_MAX`, etc.

On the iOS simulator, I logged `LONG_MAX`, `FLT_MAX` and `DBL_MAX`. Here&#39;s what I got:

    long max value: 9223372036854775807
    float max value: 340282346638528859811704183484516925440.000000
    double max value: 179769313486231570814527423731704356798070567525844996598917476803157260780028538760589558632766878171540458953514382464234321326889464182768467546703537516986049910576551282076245490090389328944075868508455133942304583236903222948165808559332123348274797826204144723168738177180919299881250404026184124858368.000000

Side note, if you use `NSNumber` it uses the appropriate type to store your number.

If you need max value for `CGFloat` you should use safely defined `CGFLOAT_MAX`.


When I create a new table that need an ordering defined by the user, my first idea always go to a column name &quot;order&quot;. Of course, this is NOT good since it&#39;s a reserved word.

Which name are you giving to that column in your database models ?

How can I convert an already cloned git repository to a shallow repository?

The git repository is downloaded through a script outside of my control so I cannot do a shallow clone.

The reason for doing this is to save disk space. (Yes, I&#39;m really short on disk space so even though a shallow repository doesn&#39;t save much, it is needed.)

I already tried 

    git repack -a -d -f -depth=1

But that actually made the repository larger.

I want to have a view in which there are vehicles driving around that the user can also drag and drop. What do you think is the best large-scale strategy for doing this? Is it best to get touch events from the views representing the vehicles, or from the larger view? Is there a simple paradigm you&#39;ve used for drag and drop that you&#39;re satisfied with? What are the drawbacks of different strategies?

I&#39;d like to test my app functions well in low memory conditions, but it&#39;s difficult to test.  How can I induce low memory warnings that trigger the didReceiveMemoryWarning method in my views when the app is running on the device, not the simulator?  Or what are some ways I can test my app under these possible conditions?

The reason I can&#39;t use the simulator is my app uses Game Center and invites don&#39;t work on the simulator.

Is there a difference between these two statements inside a function?

    bool returnValue = true;
    // Code that does something
    return(returnValue);

and this?

    bool returnValue = true;
    // Code
    return returnValue;

The former has parentheses around `returnValue`.

Are parentheses around the result significant in a return statement?

Is there something like `startsWith(str_a, str_b)` in the standard C library?

It should take pointers to two strings that end with nullbytes, and tell me whether the first one also appears completely at the beginning of the second one.

    &quot;abc&quot;, &quot;abcdef&quot; -&gt; true

How can I see the values of `delegate.myData` or `indexPath.row` in the Debugger? `delegate.myData` should be an array and `indexPath.row` an `int`. I can only see memory addresses of the objects `delegate` and `indexPath` but where are `myData` and `row`?

How could I determine the number of days between two `NSDate` values (taking into consideration time as well)?

The `NSDate` values are in whatever form `[NSDate date]` takes.

Specifically, when a user enters the inactive state in my iPhone app, I store the following value:

    exitDate = [NSDate date];

And when they open the app back up, I get the current time:

    NSDate *now = [NSDate date];

Now I&#39;d like to implement the following:

    -(int)numberOfDaysBetweenStartDate:exitDate andEndDate:now

Usually when I write anything in C++ and I need to convert a `char` into an `int` I simply make a new `int` equal to the char. 

I used the code(snippet) 


     string word;  
     openfile &gt;&gt; word;
     double lol=word;


I receive the error that 

    Code1.cpp cannot convert `std::string&#39; to `double&#39; in initialization 

What does the error mean exactly? The first word is the number 50. Thanks :)

C++ string to double conversion

So I have a double set to equal 1234, I want to move a decimal place over to make it 12.34

So to do this I multiply .1 to 1234 two times, kinda like this

    double x = 1234;
    for(int i=1;i&lt;=2;i++)
    {
      x = x*.1;
    }
    System.out.println(x);

This will print the result, &quot;12.340000000000002&quot;

Is there a way, without simply formatting it to two decimal places, to have the double store 12.34 correctly?
