sqrt()

Returns the square root of a positive integer or real number. If the parameter is a negative integer or negative real number, it is changed to a complex and then the square root is calculated.

Syntax:

sqrt(x);

where

x is a positive integer or real number, a square root of the number is calculated.

x is a negative integer or real number, the number is converted to a complex number by making x be the REAL part of the complex and setting the IMAGINARY part of the complex to 0.0. Then the square root of the new complex number is calculated.

x is a complex number, the square root of the complex number is calculated.

x is 0, then the answer is 0.0

Example:

decl x,y,z;
x = sqrt(25);      // 5
y = sqrt(-25);     // 0 + 5i
z = sqrt(-25+5i);  // .497543 + 5.02469i
