### π **Part 1: Introduction**

**Definition**

The **CEILING function** in Microsoft Excel rounds a number up, away from zero, to the nearest multiple of a specified significance.

**Purpose**

The primary purpose of the CEILING function is to round values up to a desired level of precision or significance. For instance, if you wish to avoid using pennies in your prices and your product is priced at $4.42, you can use the CEILING function to round prices up to the nearest nickel.

**Syntax & Arguments**

`CEILING(number, significance)`

**Number**: The value you want to round.**Significance**: The multiple to which you want to round.

**Return Value**

The function returns the number rounded to the nearest multiple of the specified significance.

**Remarks**

- If either argument is nonnumeric, CEILING returns the #VALUE! Error value.
- Regardless of the sign of the number, a value is rounded up when adjusted away from zero.
- If the number is an exact multiple of significance, no rounding occurs.
- If the number and significance are negative, the value is rounded down, away from zero.
- The value is rounded up towards zero if the number is negative and the significance is positive.
