Previous changes from v0.16.0
👍 This version implements major changes; most importantly, Scala 2.10 has been dropped. The commutative ring tower has been precised: Euclidean division has better semantics, and unique factorization domains have been introduced, generalizing
spire.math.prime. Some species of division with remainder are now described by
TruncatedDivision. An involution typeclass abstracts over complex conjugation. We also revised the use of commutative vs. noncommtutative rings, mostly in the construction of complex numbers/quaternions, and in the definition of modules.
🚚 Preliminary work has been done towards the modularization of Spire. A
platformmodule abstracts over the JVM/JS differences, while
Opthas been moved to the
utilmodule. Other modules are not used yet (
legacy) but will be in the future.
