A float is basically a number with decimals in it. As opposed to an integer, which is a whole number. You can make a float like this:

float someNumber = 1.2345;

NSLog(@"%f", someNumber);

That second line allows you to read the value in the console. Sometimes it's useful to put a float into a string, (which is what I did above), but it looks better like this:

float someNumber = 1.2345;

NSString *myString = [NSString stringWithFormat:@"float = %f", someNumber];
