Integers are represented as a sequence of digits. Floats use ‘.’ as a decimal separator. Either
type of number may be preceded by ‘-’ or ‘+’ to indicate a negative or positive value,
respectively.
Examples of valid integers:
21
0
-28
Examples of valid floating-point numbers:
317.24
-450187.6809
18.00
If an integer is used in a floating-point context, it will be interpreted as the equivalent floating-
point number; furthermore, if an integer exceeds the platform limits for the integer value, a
floating point value will be used instead.
