Hi! Who have expirence with C166 math library. I have a grate and interesting problem with using Sin,Cos, Asin, Acos ant etc. Asin work only in one point asin(1)=1.57, but all others break program to trap 0A (Illegal Word Operand Access Flag). I use sqrt from library and everything is OK. There are no problem with stak, I checked it with interupt routine. Also OK with RAM and ROM volume. Help who know anything abt library problem. Thank you Jury
Did you try with simulation to be sure that problem come from library. I did try with this loop: for (i=0; i<10;i++) printf("%g %g\n",sin(0.1*i),asin(sin(0.1*i))) and all returned values are ok. Bruno
