🦊 inari

A Rust implementation of set-based interval arithmetic.

Requirements

The nightly Rust toolchain is required, since the new asm! macro is used in the crate.

There is one conditional feature:

• gmp (enabled by default) - Enables operations that depend on GMP and MPFR, namely transcendental functions and conversion between texts and intervals. You can opt-out the feature to reduce dependency. Even in that case, you can still access to basic arithmetic operations that are required for writing filters for geometric predicates.
