@TRUNC

The TRUNC function will truncate the given numeric value to the specified position either before or after the decimal. The first parameter to the function is the value to be truncated and will be evaluated as either a decimal or integral number, matching the context of the function call. The second parameter is evaluated as an integral number and specifies the precision, or number of digits to which the value should be truncated. A positive precision value counts the number of digits to the right of the decimal, while a negative precision counts them to the left of the decimal. Note that this function differs from the ROUND function in that no rounding occurs. The number is truncated to the specified precision with no rounding behavior.

Parameters

    @TRUNC (Number [, Precision])
  • Number Required parameter; evaluated as either an integral or decimal number matching the context of the function call. Contains the value to be truncated by the function.
  • Precision Optional integral number parameter; contains the value specifying the precision of the resulting truncation. Positive values indicate the number of places to the right of the decimal, while negative values indicate the number of places to the left.

Supported Return Types

  • Integral Number
  • Decimal Number
