The ISO.CEILING function returns a number that is rounded up to the nearest integer or to the nearest multiple of significance.

  • This function was introduced in Excel 2010 and so is not available in earlier versions.

Syntax

=ISO.CEILING(number,[significance])

Arguments

Argument Description
number The value to be rounded
[significance] Optional. The multiple to which number is to be rounded

  If [significance] is omitted, its default value is 1

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, i.e. regardless of the sign of the number, the number is rounded up.
