Pick your number type with Spire
summary
Spire is a Scala numeric library that supplies type classes and concrete types (Rational, Algebraic, Interval, Complex, BigInt/BigDecimal, unsigned ints and custom cyclotomic numbers), plus law-driven tests and a mini-spire 2,000-line extraction. A Mandelbrot benchmark shows generic specialization matches hand-written JVM performance (float vs double comparable), while JS and native show regressions; Spire spans ~33k LOC, eight years old, not yet 1.0, and faces boxing, specialization and maintenance trade-offs.
