Small, dependency-free math utilities
- repo _repo mathkit, bootstrapped by "zzmq.dev@gmail.com[maint]" via `zz work` (remote).
- file index.js Export gcd function alongside lcm and update index.js to re-export gcd
- file src/isPrime.js Implements and exports isPrime, a function that validates its argument is a finite integer greater than 1 and determines primality by trial division up to the square root, returning true for primes and false otherwise.
- file test/isPrime.test.js Contains node:test unit tests for isPrime, verifying correct true results for known primes, false results for composites, edge cases, negative numbers, zero, one, non‑integers, NaN and infinite values.
- file src/lcm.js Export gcd function alongside lcm and update index.js to re-export gcd
- file test/lcm.test.js Add lcm function with implementation, tests, and export
- changeset changesets/2c53fff83b47376761f4fd403129f6388831860d Added the isPrime utility with export in the package entry point and introduced comprehensive tests to validate its correctness across typical, edge, and invalid inputs.
- filechange changesets/2c53fff83b47376761f4fd403129f6388831860d/index.js Provides the public API of the mathkit package, exporting the sum function and re‑exporting utility functions isOdd, isEven, min, and the newly added isPrime from their respective modules.
