Here's how to get the ceiling and floor of a float variable. Floor is truncating the decimal portion (rounding down). Ceiling is rounding up the variable.
Take the number 9.45: The floor is 9. The ceiling is 10.
If you want a number to be rounded normally, just typecast by turning the variable into a short or long.
float fNumber short iNumber set fNumber to 9.45 set iNumber to fNumber ;iNumber is now 9
It's only a bit more involved to get the floor. You basically just mod out the decimal portion and subtract.
float fNumber short iNumber set fNumber to 9.45 set iNumber to fNumber - (fNumber % 1) ;iNumber is now 9
And now the ceiling.
float fNumber short iNumber set fNumber to 9.45 set iNumber to (fNumber - (fNumber % 1)) + 1 ;iNumber is now 10
