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 number.
Remark
· 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 or omitted, 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.
