The **CEILING MATH** (CEILING.MATH) is a *Math* function that rounds a given number up to the nearest multiple of significance. This function has been released with 2013 version as a replacement for the **CEILING** function. In this guide, we’re going to show you how to use the **CEILING MATH **function and also go over some tips and error handling methods.

# Supported versions

- Excel 2013 and newer

# Excel CEILING MATH Function Syntax

# Arguments

number | The number you want to round up. |

[significance] | Optional. The multiple to which you want to round. The default is 1. |

[mode] |
Use a negative number to change the direction of the rounding for negative numbers. |

Examples

### Rounding up to the nearest integer

If both optional arguments are omitted, the **CEILING.MATH** function rounds the **number** argument up to the nearest integer. The directions is away from 0 for negative numbers as well.

### Rounding up to the nearest multiple of significance

Enter a **[significance] **value to round the **number **up to a specified multiple. You can use decimal value as well as integers. If you add a **[significance]** without the **[mode]** argument, **CEILING.MATH** rounds negative numbers away from zero by default.

### Rounding up to the nearest multiple of significance by mode

The **[mode]** argument specifies the rounding direction only for __negative__ numbers. Any value other than zero (0), the default value, reverts the direction. Thus, the **CEILING.MATH** starts to round negative numbers away from zero.

=CEILING.MATH(-23.254,-0.04,0) returns -23.24

# Tips

- Excel released the
**CEILING.MATH**function as a successor of the**CEILING**function. The support for**CEILING**function continues to not break backward compatibility. - Use the
**FLOOR.MATH**function to round up to the nearest multiple. - If you need to round up to the nearest multiple, use
**MROUND** - The
**[mode]**argument doesn't have any effect on positive numbers.
