The Infinite-Precision Calculator 1.0 is capable of representing real numbers with as many decimal places as your machine has the memory to store. It compiles cleanly. It is guaranteed free of memory errors (courtesy of valgrind). The mathematical engine is completely documented using Doxygen, making the code design sufficiently transparent that even a layman can understand the programming logic. And one time, it saved a drowning puppy. All this, and it was coded in one evening, merely awaiting the arrival of the Gtk+ front-end.
