Calculate 200^300 with SOLVE
I use this short program on my 42S to get an approximate answer for exponentiation of large arguments, e.g. 200^300 = 2.037x10^690
00 {15Byte Prgm} 01 LBL "~Y↑X" 02 X<>Y 03 LOG 04 x 05 IP 06 LASTX 07 FP 08 10↑X 09 END 200 <ENTER> 300 <XEQ> ~Y↑X gives X:2.03703597073 Y:690 Playing with my newly acquired 17BII I came up with the following SOLVE equation (works also on the 17BII+): ~Y'X: 0xL(E:IP(L(M1:LOG(Y)xX)))+ 0xL(M:ALOG(FP(G(M1))))+ IF(S(MANT):MANTG(M):EXPG(E))=0 SOLVE is fun to use and amazingly powerful.
