An educational Ruby C extension implementing the Eisel-Lemire algorithm for string-to-float conversion. This gem demonstrates why this optimization, despite being ~2.6x faster for complex numbers, was NOT submitted to Ruby core: it regresses performance by ~9% on simple numbers (the common case). Use this gem to learn about float parsing algorithms and their tradeoffs, or if you specifically work with high-precision scientific data.
