About:
The OCaml Num library provides core support for arbitrary-precision arithmetic, enabling precise calculations with integers and rational numbers that exceed standard machine word sizes. Although superseded by the Zarith library in modern OCaml, it remains a crucial dependency for legacy codebases and older packages requiring robust mathematical operations.
Key Features:
  • Arbitrary-precision integers (Big_int)
  • Arbitrary-precision rational numbers (Ratio)
  • Compatibility layer for legacy OCaml code
  • Standalone library independent of the main OCaml runtime
Use Cases:
  • Maintaining and building legacy OCaml projects that depend on the Num library
  • Performing cryptographic calculations requiring large integer arithmetic
  • Scientific computing applications needing high-precision rational numbers
Alternatives:
  • Zarith – The modern standard for arbitrary-precision arithmetic in OCaml, offering better performance and native integration.
