The 'complex' type and rudimentary operations on complex numbers are supported, but the math library is missing all of the transcendental functions on complex numbers. There is some ongoing work in the area, but due to time constraints, it will likely be a while before we have complete support. In the mean time, you can see /usr/include/complex.h for a list of supported functions. I recall someone mentioning that there is a port that provides most of the missing functionality.
