This Excel Tutorial demonstrates how to use the Excel FLOOR Function in Excel to round a number down, with formula examples.

FLOOR Function Description:

The FLOOR Function Rounds a number down, to the nearest specified multiple.

Formula Examples:

Example	Formula	Result
1	=FLOOR(C5,D5)	0
2	=FLOOR(C6,D6)	5
3	=FLOOR(C7,D7)	0.1
4	=FLOOR(C8,D8)	-20
5	=FLOOR(C9,D9)	-0.2

Syntax and Arguments:

The Syntax for the FLOOR Formula is:

Function Arguments ( Inputs ):

number – A number.

significance – The multiple to which to round the number. The sign much match the number. So if the number is negative, the significance must also be negative.

FLOOR Examples in VBA

You can also use the FLOOR function in VBA. Type:
application.worksheetfunction.floor(number,significance)
For the function arguments (number, etc.), you can either enter them directly into the function, or define variables to use instead.
