Cargo Features

[dependencies]
pymath = { version = "0.1.5", default-features = false, features = ["complex", "num-bigint", "malachite-bigint", "mul_add"] }

default = complex

The complex feature is set by default whenever pymath is added without default-features = false somewhere in the dependency tree.

complex default

Enables num-complex

Affects pymath::cmath, m::sincos, m::sincos, m_rust::sincos…

num-bigint = _bigint

Enables num-bigint

malachite-bigint = _bigint

Enables malachite-bigint

malachite upgrades minor version a lot

_bigint malachite-bigint? num-bigint?

Internal feature. User must use num-bigint or malachite-bigint instead.

Enables num-integer and num-traits

Affects math::integer…

mul_add

Do not enable this feature unless you really need it. CPython didn't intend to use FMA for its math library. This project uses this feature in CI to verify the code doesn't have additional bugs on aarch64-apple-darwin. However, this does not mean that using this feature is better or more correct on that platform. Note that the quality of the results has been well-tested without FMA but has not been tested with FMA.
