What the function does

Overview

Rounds a number up to the nearest multiple of significance.

The CEILING function is used to round a number upwards, away from zero, to the nearest multiple of a specified significance. This is particularly useful in scenarios where you need to ensure a value meets a minimum increment, such as pricing items in specific denominations or scheduling tasks in fixed time blocks. For example, CEILING(2.3, 0.5) would return 2.5, as 2.5 is the smallest multiple of 0.5 that is greater than or equal to 2.3. Both `number` and `significance` must have the same sign; if they don't, the function will return a #NUM! error. If `number` is an exact multiple of `significance`, no rounding occurs. This function is part of a family of rounding functions, including CEILING.MATH and CEILING.PRECISE, which offer more flexible handling of negative numbers.

Avoid these issues

Common Errors

1

#NUM!

Cause: The 'number' and 'significance' arguments have different signs.

Fix: Ensure both 'number' and 'significance' are either both positive or both negative. If you need to handle mixed signs, consider CEILING.MATH or CEILING.PRECISE.

2

#VALUE!

Cause: One or both arguments are non-numeric.

Fix: Verify that 'number' and 'significance' are valid numeric values or references to cells containing numbers.
