The _ROUND function rounds to the closest INTEGER, LONG or _INTEGER64 numerical value. (If the value ends with .5, it rounds instead to the closest EVEN integer value.)
Syntax
- value = _ROUND(number)
Description
- Can round SINGLE, DOUBLE or _FLOAT floating decimal point parameter values.
- Can be used when numerical values exceed the limits of CINT or CLNG.
- If the number to be rounded is less than 0.5, then it rounds down to the closest integer value.
- If the number to be rounded is greater than 0.5, then it rounds up to the closest integer value.
- If the number to be rounded ends in 0.5, rounding is done to the closest even integer value.
Example: Displays how QB64 rounds to the closest even integer value.
