For Leaf, I need to parse decimal numbers to retain the exact value of the input without rounding. I assumed such a library would exist in C++, but nothing I found handled decimal values directly. After considering several libraries, I ended up using GMP and wrote a small parsing routine. I will go into some background on why I’m doing this in a followup article.
