Release 0.4.0 (2021-03-05)

• rand support has been updated to 0.8, requiring Rust 1.36.

Contributors: @cuviper

Release 0.3.1 (2020-10-29)

• Clarify the license specification as “MIT OR Apache-2.0”.

Contributors: @cuviper

Release 0.3.0 (2020-06-13)

Enhancements

• The new “libm” feature passes through to num-traits, enabling Float features on no-std builds.

Breaking Changes

• num-complex now requires Rust 1.31 or greater.
  • The “i128” opt-in feature was removed, now always available.
• Updated public dependences:
  • rand support has been updated to 0.7, requiring Rust 1.32.
• Methods for T: Float now take values instead of references, most notably affecting the constructor from_polar.

Release 0.2.4 (2020-01-09)

• Complex::new is now a const fn for Rust 1.31 and later.
• Updated the autocfg build dependency to 1.0.

Contributors: @burrbull, @cuviper, @dingelish

Release 0.2.3 (2019-06-11)

• Complex::sqrt() is now more accurate for negative reals.
• Complex::cbrt() computes the principal cube root.

Contributors: @cuviper

Release 0.2.2 (2019-06-10)

• Complex::l1_norm() computes the Manhattan distance from the origin.
• Complex::fdiv() and finv() use floating-point for inversion, which may avoid overflows for some inputs, at the cost of trigonometric rounding.
• Complex now implements num_traits::MulAdd and MulAddAssign.
• Complex now implements Zero::set_zero and One::set_one.
• Complex now implements num_traits::Pow and adds powi and powu.

Release 0.2.1 (2018-10-08)

• Complex now implements ToPrimitive, FromPrimitive, AsPrimitive, and NumCast.

Contributors: @cuviper, @termoshtt

Release 0.2.0 (2018-05-24)

Enhancements

• Complex now implements num_traits::Inv and One::is_one.
• Complex now implements Sum and Product.
• Complex now supports i128 and u128 components with Rust 1.26+.
• Complex now optionally supports rand 0.5, implementing the Standard distribution and a generic ComplexDistribution.
• Rem with a scalar divisor now avoids norm_sqr overflow.

Breaking Changes

• num-complex now requires rustc 1.15 or greater.
• There is now a std feature, enabled by default, along with the implication that building without this feature makes this a #![no_std] crate. A few methods now require FloatCore, and the remaining methods based on Float are only supported with std.
• The serde dependency has been updated to 1.0, and rustc-serialize is no longer supported by num-complex.

Release 0.1.43 (2018-03-08)

• Fix a usage typo in README.md.

Contributors: @shingtaklam1324

Release 0.1.42 (2018-02-07)

• num-complex now has its own source repository at rust-num/num-complex.
