Spire is a numeric library for Scala providing powerful new number types (like Rational, Complex, and more) and generic numeric abstractions via type classes. It aims to be fast and precise, using specialization and macros so generic code performs like hand-written numeric code.

Use cases

• perform exact arithmetic with rational numbers in Scala
• write generic numeric algorithms without baking in a numeric type
• use complex numbers, intervals, and other number types in Scala
• avoid boxing overhead in generic numeric code
• implement math-heavy libraries with type class abstractions

When to choose

• you need precise or arbitrary-precision numeric types on the JVM or Scala.js
• you want generic numeric code with performance comparable to direct implementations
• you're in the Typelevel/Scala ecosystem and want algebraic type classes

When to avoid

• you're not working in Scala
• you only need simple built-in Int/Double arithmetic
• you need GPU or vectorized numeric computing
