**Public Function RealPart( _
ByVal vX As Variant _
) As Variant**

**"Real Part" **

Return the real part of a complex (or real) number.

Function returns vX unchanged if vX is already a real number.

**Examples:** RealPart(45) = 45
RealPart("23|45") = 23
RealPart("-34.5|12") = -34.5
IsNull(RealPart(Null)) = True

**See also:** ImagPart Function
ComplexStringToReals Function

**vX:** The number whose real part is to be returned. Function returns Null if vX is Null or cannot be fixed up to a real or complex number (as defined by the ComplexStringToReals function). Complex numbers are represented within strings as "R|I" where R is the real part and I is the imaginary part. Copyright 1996-1999 Entisoft
