How can I support very big integers?
Else maybe check this. It's a header-file only BigInt library. I don't have time to look into the algorithm in detail right now, but it seems readable
What are some alternatives?
When comparing BigInt and infint you can also consider the following projects:
ric-script - A modern scripting language; implemented in old school C, yacc & flex
LibTomMath - LibTomMath is a free open source portable number theoretic multiple-precision integer library written entirely in C.
seed7 - Source code of Seed7
gmp-wasm - Fork of the GNU Multiple Precision Arithmetic Library (GMP), suitable for compilation into WebAssembly.
