The _ROUND function rounds to the closest even INTEGER, LONG or _INTEGER64 numerical 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.
• Rounding is done to the closest even INTEGER value. The same as QBasic does with []().
