Summary
Returns an integral number, whose value depends upon the nature of the parameter's numeric value:
- If that numeric value is positive but is not an exact integer, the number returned is the largest integer that is smaller in value than the parameter's numeric value.
- If that numeric value is negative but is not an exact integer, the number returned is the smallest integer that is larger in value than the parameter's numeric value.
- If that numeric value is an exact integer, the number returned has exactly the same value.
