Realpart

Function: realpart (<expr>) Returns the real part of <expr>. realpart and imagpart will work on expressions involving trigonometic and hyperbolic functions, as well as square root, logarithm, and exponentiation.

x,y:real;
z:x+%i*y;
w:(z-%i)/(z+%i);
x1:realpart(w);
y1:imagpart(w);

(%o1)                                true
