Truncates a number by removing decimal places.
Syntax:
TRUNC(number, places)
returns number with at most places decimal places. Excess decimal places are simply removed, irrespective of sign. TRUNC(number; 0) behaves as INT(number) for positive numbers, but effectively rounds towards zero for negative numbers.
Example:
TRUNC(1.239, 2)
returns 1.23. The 9 is lost.
TRUNC(-1.234999, 3)
returns -1.234. All the 9s are lost.
