TRUNCATE

Returns the number X, truncated to D decimal places. If D is 0, the result has no decimal point or fractional part. D can be negative to cause D digits left of the decimal point of the value X to become zero. The maximum absolute value for D is 30; any digits in excess of 30 (or -30) are truncated.
