Usage

Use the ISO.CEILING formula with the syntax shown below, it has 1 required parameter and 1 optional parameter:

=ISO.CEILING(number, [significance])

1. number (required):
   The value to be rounded up.
2. significance (optional):
   The multiple to which to round up. If omitted, the number is rounded up to the nearest integer.

Examples

Rounding up to the nearest multiple

Use ISO.CEILING to round a number up to the nearest multiple of a specified value. For example, if you need to round up to the nearest 10, use ISO.CEILING(A1, 10).

Rounding up for financial calculations

Use ISO.CEILING to round values up to meet financial regulations or standards. For example, some tax laws require certain values to be rounded up to the nearest dollar.

Calculating project timelines

Use ISO.CEILING to round up time values to the nearest hour or day. This can be useful when calculating project timelines or billing hours.

Common Mistakes

Incorrect number of arguments

Users may forget to provide one or both of the required arguments for the ISO.CEILING formula. Ensure that both the number and significance arguments are included in the formula.

Invalid input type

The number and significance arguments must be numerical values. Ensure that the input types are correct and there are no additional characters or spaces in the formula.

Incorrect use of decimal places

The significance argument must be a positive integer. Users may accidentally include decimal places or negative values in the significance argument, which will produce an error. Ensure that the significance argument is a positive integer.

Incorrect rounding

The ISO.CEILING formula rounds up to the nearest multiple of the significance argument. If the number is already a multiple of the significance argument, it will not be rounded up. Ensure that the rounding is correct and matches the desired output.

Misunderstanding of ISO standard

The ISO standard for rounding up to a multiple involves rounding up to the next highest multiple, even if the number is already a multiple. Ensure that the user understands this standard and uses it correctly in their formula.
