ROUNDDOWN

Rounds a number down, toward zero.

Syntax

ROUNDDOWN(number,num_digits)

Number is any real number that you want rounded down.

Num_digits is the number of digits to which you want to round the number.

Remarks

ROUNDDOWN behaves like ROUND, except that it always rounds a number down.
If num_digits is greater than 0 (zero), then number is rounded down to the specified number of decimal places.
If num_digits is 0, then number is rounded down to the nearest integer.
If num_digits is less than 0, then number is rounded down to the left of the decimal point.
