Complex Power Function
Standard Library Header file :
complex.h (complex arithmetic)
Introduction
In mathematics complex number is denoted by 'z' .
z = x + iy
In this number 'x' is the real part and 'y' is imaginary part.
'i' is imaginary unit ,where "i2 = -1 ".
Complex power is defined by the mathematical operation of exponentiation given by "z1z2" .
In C programming language , library function for this is given by Cpow.
Syntax for function
double complex cpow(double complex x, double complex y);
Return Value
These functions shall return the complex power function value.
Returns the complex power of base x raised to the y-th power using the principal branch, whose cuts are along the negative real axis.
