4.4 Elementary complex functions

The class cl_N defines the following operation:

cl_N complex (const cl_R& a, const cl_R& b)

Returns the complex number a+bi, that is, the complex number with real part a and imaginary part b.

Each of the classes cl_N, cl_R defines the following operations:

cl_R realpart (const type& x)

Returns the real part of x.

cl_R imagpart (const type& x)

Returns the imaginary part of x.

type conjugate (const type& x)

Returns the complex conjugate of x.

We have the relations

• x = complex(realpart(x), imagpart(x))
• conjugate(x) = complex(realpart(x), -imagpart(x))
