How to Use the ISO.CEILING Function in Excel

The ISO.CEILING function in Excel and Google Sheets is designed to round numbers up to the nearest multiple specified by the user, in accordance with ISO standards. This function is particularly useful when calculations need to be standardized to comply with ISO regulations or when rounding numbers up based on a specified multiple.

Syntax:

The syntax for the ISO.CEILING function is consistent across both Excel and Google Sheets:

ISO.CEILING(number, significance)
  • number: The numerical value you wish to round up.
  • significance: The multiple to which you intend to round the number.

Examples:

Let’s examine some examples to understand how the ISO.CEILING function operates:

Rounding up to the nearest multiple:

Consider the following numbers that need to be rounded up to the nearest multiple of 5:

Number Rounded
17 =ISO.CEILING(17, 5)
32 =ISO.CEILING(32, 5)

Using the ISO.CEILING function, the numbers 17 and 32 are rounded up to 20 and 35, respectively. This illustrates how the function effectively rounds numbers to the nearest specified multiple, in this case, 5.

Ensuring compliance with ISO standards:

Consider a scenario where you’re handling financial data that must adhere to ISO standards for rounding. Assume there’s a price list where every price needs to be rounded up to the nearest 0.05, as per these standards.

This can be accomplished using the ISO.CEILING function:

=ISO.CEILING(A2, 0.05)

In this example, if cell A2 holds the original price, applying the ISO.CEILING function with a significance of 0.05 ensures that all prices are rounded up to the nearest 0.05.

Integrating the ISO.CEILING function into your Excel or Google Sheets formulas enables easy rounding of numbers to designated multiples, aiding in the adherence to ISO standards and other precise rounding requirements.
