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

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)
