RE: CAS precision
Does using return(param) within a subroutine truncate any digits? One of the issues I have found is that matrix multiplication (row vector times column vector) gives me a slightly different result than calling a subroutine that does the multiplication and returns the inner product (the former is more accurate than the latter it seems). That is, t:=b*v; seems more accurate in the long run (which I use later on to for something else) than t:=inprod(b,v); where inprod(); is a cas routine whose code is:
Code: inprod(b,v):= Graph 3D  QPI  SolveSys
