## Purpose

## Return value

## Arguments

*number*- The number that should be rounded.*significance*- [optional] Multiple to use when rounding. Default is 1.

## Syntax

## How to use

The Excel FLOOR.PRECISE function rounds a number *down* to a given multiple, where multiple is provided as the *significance* argument. If the number is already an exact multiple, no rounding occurs and the original number is returned.

The FLOOR.PRECISE function takes two arguments, *number *and *significance. *The *number* argument is the numeric value to round down, and is the only required argument. With no other input, CEILING.PRECISE will round *number* up to the next integer.

The *significance* argument is the multiple to which *number* should be rounded. In most cases, *significance* is provided as a numeric value, but FLOOR.PRECISE can also understand time entered as text like "0:15". The default value of *significance* is 1.

### Examples

By default, FLOOR.PRECISE rounds down to the next integer, with a *significance* of 1.

```
=FLOOR.PRECISE(3.75) // returns 3
=FLOOR.PRECISE(8.9) // returns 8
```

To round to a different multiple, provide a value for *significance* :

```
=FLOOR.PRECISE(5.75,3) // returns 3
=FLOOR.PRECISE(5.75,2) // returns 4
=FLOOR.PRECISE(5.75,0.5) // returns 5.5
```

### Rounding negative numbers

The FLOOR.PRECISE function always rounds negative numbers down away from zero, and ignores the sign of significance.

```
=FLOOR.PRECISE(-4.1) // returns -5
=FLOOR.PRECISE(-4.1,1) // returns -5
=FLOOR.PRECISE(-4.1,-1) // returns -5
```

### FLOOR.PRECISE vs FLOOR

The FLOOR.PRECISE function differs from the FLOOR function in these ways:

- Provides a default
*significance*of 1, rounding to nearest integer - Always rounds negative numbers down away from zero
- Ignores the sign of
*significance*(uses the absolute value)

### Notes

- FLOOR.PRECISE always rounds negative down away from zero.
- If
*number*is an exact multiple of significance, no rounding occurs. - To round to the
*nearest*multiple*(*up or down) see the MROUND function.
