One thing I forgot is that I'd like to convert complex<sint16> to a single sint16 with just the "real" part, like I can convert complex<float> to single float. It doesn't look like there is the equivalent of Complex To Real for integers. Is there an alternative to converting to floating point and back? -Marc _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
