D trunc

Type Function: DINT

Input X	REAL (input)
Output	DINT (output value)
	D _TRUNC returns the integer value of a REAL value as DINT. The IEC routine TRUNC() does not supports on all systems a TRUNC to DINT so that we have rebuilt this routine for compatibility. Unfortunately, even REAL_TO_DINT does not give on all systems the same result. D_TRUNC reviewes what result the IEC functions provides, and uses the appropriate function to deliver a useful result.
	D_TRUNC(1.6) = 1
	D_TRUNC(-1.6) = -1
