Sorry, you are right. I confused the two issues. I had to add: mp_int operator - () const; //unary negate.
You are right this function needs to be added. I implemented this as free function now.
operation. When I changed the %= to reflect that the value was the remainder it worked. Why is it that you add the rhs in the event that the sign of the remainder is not the same as the rhs term?
I don't know, it's what libtommath does so I just did the same ;-) I've always wanted to change it, but somehow forgot about it. It will now give the expected result.
The pattern seems to be that subtracting maxLong from den nets a +2 gain on den. den values: 185745031 185745033 185745035 185745037
Okay I will look into it, btw there's a mp_int<>::print() function which prints the internal representation to cout.
P.S. Let me know if I can be of any more assistance.
Oh you're doing well, just keep on testing. I will upload a new version with the bugfixes to the vault soon. Thanks for your help, Kevin
