This section provides benchmarks for the udecimal library in comparision with other libraries. Some benchmarks have fallback suffix which means the operation can’t be done by using u128 and falls back to big.Int API.
NOTE: The results are for references and can be varied depending on the hardware
goos: linux
goarch: amd64
pkg: github.com/quagmt/udecimal/benchmarks
