TRUNC Function

Truncates a numeric variable or string to a specified number of decimal places. See also the ROUND function.

Syntax

TRUNC(number, places)

Syntax Elements

number is the numeric variable or string.

places is the number of decimal places that will be retained after truncation.

Operation

If the number of decimal places exceeds the current precision, TRUNC will affect only those numbers that have not already been shortened as a result of operations determined by the PRECISION statement.

Negative numbers are treated similarly (unwanted decimal places are discarded), but the sign is retained.

Example

A = 153.5673

B = TRUNC(A,2)

PRINT B

prints 153.56.
