Numeric rint()Usage
If two double values that are mathematical integers are equally close, the result is the integer value that is even.
Special cases:
- If the value is already equal to a mathematical integer, then the result is the same as the value.
- If the value is NaN or an infinity or positive zero or negative zero, then the result is the same as the value.
