Implements the analogs of the unary arithmetic operators for complex numbers.
1) Returns the value of its argument
2) Negates the argument
[edit] Parameters
val
-
the complex number argument
[edit] Return value
1) a copy of the argument, std::complex <T>(val)
2) negated argument, std::complex <T>(-val.real(), -val.imag())
[edit] See also
performs complex number arithmetic on two complex values or a complex and a scalar
