Introduction to the floor function of Excel

Function Name: FLOOR

Function: Rounds the parameter number down in the direction in which the absolute value is reduced, making it equal to the nearest significance.

function syntax: FLOOR (number,significance)

Introduction to function Parameters:

Number to be rounded.

Significance base.

Parameter description:

• If either parameter is a non-numeric argument, FLOOR returns the error value #VALUE!.

• If the number and significance symbols are the opposite, the function FLOOR returns the error value #NUM!.

• The absolute value of the parameter is reduced regardless of the number's positive or negative numbers. If number happens to be a multiple of significance, no rounding is required.

Floor function Instance

FLOOR (1.3,0.5) equals 1

FLOOR (1.6,0.5) equals 1.5

FLOOR (2.5, 1), rounding 2.5 down in the direction of the absolute value so that it equals the nearest multiple of 1 (2)

FLOOR (-2.5,-2), rounding 2.5 down in the direction of the absolute value, so that it equals the nearest-2 multiplier (-2)

FLOOR (-2.5, 2) returns the error value because the symbols for-2.5 and 2 are different (#NUM!)

FLOOR (1.5, 0.1), rounding 1.5 down in the direction of the absolute value so that it equals the nearest multiple of 0.1 (1.5)

FLOOR (0.234, 0.01), rounding 0.234 down in the direction of the absolute value so that it equals the nearest multiple of 0.01 (0.23)
