    Trying to use complex.h classes, some keyword is hiding it

    I'm trying to implement a calculation which involves a sqare root and therefore has the possibility of becoming a complex number. I found that C++ has a standard complex number class which would work rather well, with multiplication and all. The only problem is somehow another keyword called complex is hiding the implementation, even when I try to use "std::complex" it says this error.

    Code:
    error: `complex' undeclared (first use this function)
    error: (Each undeclared identifier is reported only once for each function it appears in.)
    error: expected `;' before "a"
    Anyone know how I can solve this?

    May you post the interesting part of your code?

    never mind, I thought it was an updated C library, but it uses standard templates. I just needed to give it a template argument.

    By the way, remember that the header is <complex>, not <complex.h>.
    C + C++ Compiler: MinGW port of GCC
    Version Control System: Bazaar
