hello,
i've searched through the discussions but i haven't been able to find any
info on using floats with exponents in legOS, specifically the inverse of
natural log: e^. actually, i can't find any info about integers with
exponents either.  i am programming a backprop neural net to run on the RCX
that uses a sigmoid activation function: (1/(1 + e^(-D*net))). i've seen a
few posts on trig functions, but i really would prefer exponents if possible.
any suggestions/help would be appreciated.
thanks,
dave

Dave I am working on a number of maths functions that includes loge log10 expe and exp10 x^y as well as trig functions. As you note it requires the specification of the mantassa and exponent desciption of the float variable for the RCX. Usually this (...) (23 years ago, 6-Mar-02, to lugnet.robotics.rcx.legos)
