I just tried to implement the RSA public key encryption algorithm and I
have to say that it was a total breeze using DJGPP and the STL Integer
class. My next project is a custom raytracer engine that renders a scene
that is rendered inside a sphere 16 light minutes accross. Can the
normal float can handle that kind of data if 1.0 represents one metre?
Can the double? Can the long double? Does it matter? (Note: One pixel at
1024x768 represents a 6000x6000 km area at that distance.)
If the only way to do it is with "arbitary" or high precision emulate
FP, is there a class out there that can do it and be totally compatible
with the old FP math? (Ie: I just have to change a typedef somewhere to
make the switch.)
