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

ISO.CEILING(number, [significance])

The ISO.CEILING function syntax has the following arguments:

• Number    Required. The value to be rounded.

• Significance    Optional. The optional 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.

## Example

Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.
