Calculates the amount rounded up to the next multiple of significance.
CEILING(Amount, Significance)
Amount: number being rounded.
Significance (optional): multiple to which rounding is to be calculated (default value equals 1).
CEILING(5.4, 2) equals 6
CEILING(-5.4, 2) equals -4
If significance equals zero or is negative when the amount is positive, 0 is returned.
If the amount is an exact multiple of significance, no rounding occurs.
