thrust::proj

Defined in thrust/complex.h

template<typename T>
complex<T> thrust::proj(const T &z)

Returns the projection of a complex on the Riemann sphere. For all finite complex it returns the argument. For complexs with a non finite part returns (INFINITY,+/-0) where the sign of the zero matches the sign of the imaginary part of the argument.

Parameters

z – The complex argument.
