Compares two complex numbers. Scalar arguments are treated as complex numbers with the real part equal to the argument and the imaginary part set to zero.

1-3) Compares lhs and rhs for equality.
4-6) Compares lhs and rhs for inequality.

Parameters

lhs, rhs - the arguments to compare: either both complex numbers or one complex and one scalar of matching type (float, double, long double)

Return value

1-3) true if respective parts of lhs are equal to rhs, false otherwise.
4-6) !(lhs == rhs)

Notes

Overloads are marked as constexpr since c++14
