The ISO.CEILING function in Excel is a powerful tool that allows users to round numbers up to a specified level of precision. This function is particularly useful in scenarios where financial calculations or statistical analyses require rounding to align with specific standards or to ensure compliance with regulations.

Syntax

ISO.CEILING(number, significance)

• number: The value you wish to round up.
• significance: The multiple to which you want to round the number.

Example #1

ISO.CEILING(2.3, 1)

This rounds 2.3 up to the nearest integer, resulting in 3.

Example #2

ISO.CEILING(2.3, 0.5)

This rounds 2.3 up to the nearest 0.5, resulting in 2.5.

Example #3

ISO.CEILING(-2.3, 1)

For negative values, this function rounds -2.3 up to the nearest integer, which results in -2.

Error handling

• NUM!: This error occurs if the significance is less than or equal to 0, meaning that the function cannot perform the rounding operation appropriately.
• VALUE!: This error results when the number or significance provided is non-numeric, making it impossible for Excel to process the function correctly.

Conclusion

The ISO.CEILING function is an essential tool for any Excel user needing to perform precise rounding operations. By understanding its syntax and functionality, users can enhance their data analysis capabilities, ensuring that their results meet necessary financial and statistical standards.
