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)
