Hey people, I was looking at https://wiki.freebsd.org/Numerics, and we are stalling. For example, we have working code for clog and clogf - why don't we commit it? One of the reasons I bring this up is I would like to create a port for http://librsb.sourceforge.net/, and the only barriers are the lack of cpowf and cpow. Right now I intend to commit it with a rather simplistic patch: +complex float clogf(complex float a) { + return logf(cabsf(a)) + I*cargf(a); +} + +complex float cpowf(complex float a, complex float b) { + return cexpf(b*clogf(a)); +} + +complex double clog(complex double a) { + return log(cabs(a)) + I*carg(a); +} + +complex double cpow(complex double a, complex double b) { + return cexp(b*clog(a)); +} +home | help
