<complex.h> for Cygwin?
Fri Oct 1 15:08:00 GMT 2010
I need to write some simple code which involves complex values. I
remembered that C99 added support for complex values and tried to use
<complex.h> (different from C++'s <complex>) - I tried ccos() and got
the error below.
Another option is to use GLS?
