Rounds a number up, away from 0 (zero).
Syntax
ROUNDUP(number,num_digits)
Number is any real number that you want rounded up.
Num_digits is the number of digits to which you want to round the number.
Remarks

ROUNDUP behaves like ROUND, except that it always rounds a number up.

If num_digits is greater than 0 (zero), then number is rounded up to the specified number of decimal places.

If num_digits is 0, then number is rounded up to the nearest integer.

If num_digits is less than 0, then number is rounded up to the left of the decimal point.
