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

**"Phase Angle" **

Returns the phase angle of a rectangular coordinate pair represented by a complex number.

**Examples:** PhaseAngle("1|1") = 0.785398163397448
PhaseAngle("2|2") = 0.785398163397448
PhaseAngle("2|3") = 0.982793723247329
PhaseAngle("2|4") = 1.10714871779409
PhaseAngle("-2|-2") = -2.35619449019234
PhaseAngle("-2|-4") = -2.0344439357957
PhaseAngle("2|0") = 0

**vX:** Number whose phase angle is 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
