What is SO.CEILING function in Excel?

SO.CEILING functionn is one of the Math and Trig functions in Microsoft Excel that returns a number that is rounded up to the nearest integer or to the nearest multiple of significance. Regardless of the sign of the number, the number is rounded up. However, if the number or the significance is zero, zero is returned.

Syntax of SO.CEILING function

The ISO.CEILING function syntax has the following arguments:

=ISO.CEILING(4.3)	Rounds 4.3 up to nearest multiple of 1	5
=ISO.CEILING(-4.3)	Rounds -4.3 up to nearest multiple of 1	-4
=ISO.CEILING(4.3, 2)	Rounds 4.3 up to the nearest multiple of 2	6
=ISO.CEILING(4.3,-2)	rounds 4.3 up to the nearest multiple of -2	6
=ISO.CEILING(-4.3,2)	Rounds -4.3 up to the nearest multiple of 2	-4
=ISO.CEILING(-4.3,-2)	Rounds -4.3 up to the nearest multiple of -2	-4

Note: The absolute value of the multiple is used, so that the ISO.CEILING function returns the mathematical ceiling irrespective of the signs of number and significance.
