# CEILING.PRECISE Function – Google Sheets

The CEILING.PRECISE function in Google Sheets rounds a number up to the nearest integer multiple of a specified significance. This function rounds negative numbers toward zero.

CEILING.MATH, along with CEILING.PRECISE, supplant the CEILING function.

## Syntax

`=CEILING.PRECISE(number, [significance])`

`number` – The number for the function to round

`significance` – Optional. The multiple to round up to. The default value is 1.

## Possible Errors

#VALUE! – An argument is non-numeric.

## Examples

You can use CEILING.PRECISE in many different ways. Let’s take a look at a few, starting with rounding currency.

### Example 1 – Round Up to the Next Nickel

Sometimes, presenting a price rounded up to the next nickel looks better. Let’s look at how to do that.

The formula used in cell C2: `=CEILING.PRECISE(A2,B2)`

We use the CEILING.PRECISE function to round the Original Price to a significance of `\$0.05`. Google Sheets does not round the value in row 3 because \$1.25 is already a multiple of `\$0.05`. Since the function rounds up, it rounds `\$1.23` to \$1.25 in row 2 and rounds `\$1.27` up to \$1.30 in row 4.

### Example 2 – Round Up to the Nearest Half-Hour

Next, let’s round some time values. It is common to refer to a time as a rounded value. In this example, we’ll round values up to the next half-hour.

The formula used in cell C2: `=CEILING.PRECISE(A2,B2)`

⚠️ You can enter a half hour as “`0:30`” or “`0:30:00`“. Either way, you’ll need to use custom formatting to remove the seconds, like in the example above in column B.

Rows 2 and 4 both get rounded up to the next half hour. Since `1:30 PM` is already a multiple of 30 minutes, the CEILING.PRECISE function does not change it.

### Example 3 – Round With Different Significance

Up to this point, we have been changing the `number`. Now, let’s look at changing the `significance`. We’ll use positive and negative `significances` to see the difference.
