whole_num = %TRUNC(expression)
Return value
whole_num
The whole-number portion of expression. The result has the same numeric data type as expression. If expression is implied-decimal data type, the result has no fractional precision. (n)
Arguments
expression
A numeric expression to be truncated. (n)
Discussion
The difference between %TRUNC and %TRUNCATE is that with implied-decimal arguments, %TRUNC returns a result with no fractional precision and %TRUNCATE returns a result with the same fractional precision as expression.
Examples
The following intrinsic function returns the value 33.
dvar = %trunc(33.5)
