Syntax

TRUNC(value, [places])

• value - The value to be truncated.
• places - [ OPTIONAL - 0 by default ] - The number of significant digits to the right of the decimal point to retain.
  • If places is greater than the number of significant digits in value, value is returned without modification.
  • places may be negative, in which case the specified number of digits to the left of the decimal place are changed to zero. All digits to the right of the decimal place are discarded. If all digits of value are changed to zero, TRUNC simply returns 0.

Notes

• TRUNC performs no rounding, simply discarding unwanted digits.
