Syntax and arguments

FLOOR(number, significance)


  • Number: Required, the number that used to round.

Return Value

The FLOOR function returns to a numeric value.


#VALUE! error value occurs when the anyone of arguments is not a numeric value.

#NUM! error value occurs:

  • In Excel 2010 or later, when the argument number is a positive value, but the argument significance is a negative value.

If the argument number is negative, FLOOR function rounds down and goes away to zero, for example, FLOOR(-10,3)=-12.
