Hi What math functions are available under legOS? I can get the usual +-/ and * to work, but not powers or square roots. Are these math functions available and what others e.g. sine, cosine etc? I thought it would be standard C stuff like pow and (...) (24 years ago, 12-Nov-00, to lugnet.robotics.rcx.legos)

Hi there, I'm quite now on legOS (compiled my first program yesterday), and I'm trying to find a way of using lnp. Is there any HOWTO or reference for the RCX side/the host side ? Thanx in advance. (24 years ago, 10-Nov-00, to lugnet.robotics.rcx.legos)
