INTEGER
types but supporting times wider than 32 bits. Therefore, the values returned by this intrinsic might be, or become, negative, or numerically less than previous values, during a single run of the compiled program. - Standard:
- GNU extension
- Class:
- Function
- Syntax:
-
RESULT = MCLOCK()
