The significance argument rounds the number up to the nearest integer that is a multiple of the significance specified. The exception is where the number to be rounded is an integer. For example, for a significance of 3 the number is rounded up to the next integer that is a multiple of 3.

ModeOptional. For negative numbers, controls whether Number is rounded toward or away from zero.

The Mode argument does not affect positive numbers.

Rounds a number up to the nearest integer or to the nearest multiple of significance.

By default, negative numbers with decimal portions are rounded up (toward 0) to the nearest integer. For example, -6.7 is rounded up to -6.

Rounds 6.7 up to the nearest integer (7).

The CEILING.MATH function syntax has the following arguments.

Rounds -8.1 up (toward 0) to the nearest integer that is a multiple of 2 (-8).

SignificanceOptional. The multiple to which Number is to be rounded.

Rounds 24.3 up to the nearest integer that is a multiple of 5 (25).

If Number divided by a Significance of 2 or greater results in a remainder, the result is rounded up.

Rounds -5.5 down (away from 0) to the nearest integer that is a multiple of 2 with a mode of -1, which reverses rounding direction (-6).

By default, significance is +1 for positive numbers and -1 for negative numbers.

By default, positive numbers with decimal portions are rounded up to the nearest integer. For example, 6.3 is rounded up to 7.

CEILING.MATH(number, [significance], [mode])

This article describes the formula syntax and usage of theCEILING.MATHfunction in Microsoft Excel.

NumberRequired. Number must be less than 9.99E+307 and greater than -2.229E-308.

By specifying the Significance and Mode arguments, you can change the direction of the rounding for negative numbers. For example, rounding -6.3 to a significance of 1 with a mode of 1 rounds away from 0, to -7. There are many combinations of Significance and Mode values that affect rounding of negative numbers in different ways.
