Thanks for the helpful response. I've downloaded mpfr and mpfrcpp, but I'm not sure what to do exactly to include them (while I'm compiling?). Also, would it be alright if I sent you all of my code together? To be honest, I have very little idea of what I'm doing in general; it took me quite a few hours to understand just how to use custom libraries, and I'm still not sure if I've used them correctly. Thanks, Ailec
