FLOOR.MATH

Excel Functions

Round number down to nearest multiple

Syntax

EXCEL

=FLOOR.MATH(number, [significance], [mode])

Arguments

Parameter	Description
`number`	The number that should be rounded.
`significance`	[optional] Multiple to use when rounding. Default is 1.
`mode`	[optional] For rounding negative numbers toward or away from zero. Default is 0.

Return Value

A rounded number

Details

The Excel FLOOR.MATH 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.MATH function takes three arguments, number, significance, and mode. Number is the numeric value to round down, and is the only required argument. With no other input, FLOOR.MATH will round number down 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.MATH can also understand time entered as text like "0:15". The default value of significance is 1. The mode argument controls the direction negative values are rounded. By default, FLOOR.MATH

Examples

By default, FLOOR.MATH rounds to the nearest integer, using a significance of 1.

EXCEL

=FLOOR.MATH(5.75) // returns 5
=FLOOR.MATH(2.55) // returns 2

Examples

Provide a value for significance to round to a different multiple:

EXCEL

=FLOOR.MATH(5.75,1) // returns 5
=FLOOR.MATH(5.75,3) // returns 3
=FLOOR.MATH(5.75,0.5) // returns 5.5

Rounding negative numbers

Positive numbers with decimal values are rounded down to the nearest integer, and negative numbers with decimal values are rounded away from zero:

EXCEL

=FLOOR.MATH(6.7) // returns 6
=FLOOR.MATH(-6.7) // returns -7

Rounding negative numbers

Control for rounding negative numbers toward zero or away from zero is provided with the (optional) mode argument. Mode defaults to zero or FALSE. Whe

EXCEL

=FLOOR.MATH(-4.1) // returns -5
=FLOOR.MATH(-4.1,1) // returns -5
=FLOOR.MATH(-4.1,1,TRUE) // returns -4
