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

**"Square Root" **

Square root of a real or complex number.

**Examples:** Sqrt(3.4) = 1.84390889145858
Sqrt(-3.4) = "0|1.84390889145858"
Sqrt("-2|-3") = "0.895977476129838|-1.67414922803554"
Sqrt("-2|3") = "0.895977476129838|1.67414922803554"
IsNull(Sqrt(Null)) = True

**vX:** The number whose square root 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.

**Note:** Sqrt(X) is equivalent to and more accurate than NthRoot(X, 2). Copyright 1996-1999 Entisoft
