Stint (Stack-based multiprecision integers)

A fast and portable stack-based multi-precision integer library in pure Nim

Main focus:

Portability
- 32 and 64 bit arch
- ARM for usage on mobile phones
- Additionally RISC-V and MIPS for open hardware and low power IoT devices.
Speed, library is carefully tuned to produce the best assembly given the current compilers. However, the library itself does not resort to assembly for portability.
No heap/dynamic allocation
Ethereum applications
- Uint256/Int256 for Ethereum Virtual Machine usage.
- Uint2048 for Ethereum Bloom filters
Ease of use:
- Use traditional +, -, +=, etc operators like on native types
- converting to and from raw byte BigInts (also called octet string in IETF specs)
- converting to and from Hex
- converting to and from decimal strings
