Int(x)

Int returns the integer part of a value.
Note that Int truncates the decimal part of a value, which is slightly different from rounding. If you want to round a value, you should add 0.5 to it if it's a positive value or substract 0.5 from it if it's negative before using Int. For example, taking the integer part of 3.1 and 3.9 gives 3 in both cases whereas 4 would have been much more accurate in the second case.
You must then treat the integer number as a string, because when Aptilis deals with numbers, they are automatically stored as floating point values and a string of zeroes might not be what you want, especially if the value needs to be displayed.

Return value:
A string representing the integer part of x.

Example:

i = int(3.52) $
// The dollar is to avoid the '.0000'
print(i$)
