What Is the Return Data Type of Math RINT?
Understanding Math RINT
Math.rint() function works by rounding the given number to the nearest integer. If the decimal part of the number is less than 0.5, it rounds down to the nearest integer; if it is equal to or greater than 0.5, it rounds up to the nearest integer.
- The decimal part (0.3) is less than 0.5, so it rounds down to 4.
Math.rint() function does not modify the original number; instead, it returns a new rounded value.
Data Type Returned by Math RINT
The return data type of
Math.rint() is always a number, regardless of the input type provided.
- The result will be “number” since 4 is already an integer and rounding has no effect.
Note: If the input provided to
Math.rint() is not a number or cannot be converted to a number, it will return NaN (Not-a-Number).
