The [[_ROUND]] function rounds to the closest EVEN [[INTEGER]], [[LONG]] or [[_INTEGER64]] numerical value.
|

{{PageSyntax}}

|
:: value = _ROUND ({{Parameter|number}})
|

{{PageDescription}}
|
|
* Can round [[SINGLE]], [[DOUBLE]] or [[_FLOAT]] floating decimal point parameter values.
|
|
* Can be used when numerical values exceed the limits of [[CINT]] or [[CLNG]].
|
|
* Rounding is done to the closest even [[INTEGER|integer]] value. The same as Qbasic does with [[\|integer division]].
|

''Example:'' Displays how QB64 rounds to the closest even integer value.
