Spire v0.14.0 Release Notes
Release Date: 2017-03-19 // about 7 years ago-
🚀 This release is a major milestone for Spire.
First of all, it introduces a dependency on typelevel/algebra (and thus on typelevel/cats-kernel). This provides immediate compatibility with Cats and Algebird.
Second of all, Spire is now published to the org.typelevel organization (which was previously org.spire-math).
➕ Additions:
- Added GCDRing, part of the commutative ring hierarchy
- Clarified the laws of EuclideanRing
- Added DivisionRing, a ring in which division is possible (generalization of fields to the noncommutative case; used now by Spire's quaternions).
🔄 Changes:
- Many type classes are now aliases to algebra's type classes
- Algebra provides commutative rings and fields, but the intemediate structures (GCDRing/EuclideanRing) are added by Spire; thus Spire Field differs from algebra Field by extending GCDRing and EuclideanRing.
- The EuclidenRing operations for Field have been corrected; in particular, Float, Double no longer perform truncated division but a /~ b = 0 for nonzero b, as a can always be divided by b in a field.
- Signed now extends Order, thus IsReal only extends Signed.
- IsReal has been replaced by Signed for some operations in e.g. Complex, making them more precise/general.
- Many different efficiency improvements
🛠 Fixes:
- Instances for Complex and Quaternion are more precise
Numeric[Complex[A]]is no longer provided- Many bug fixes
