Version 1.6.0 (unreleased)
|
||
==========================
|
||
|
||
* The crate now requires rustc version 1.47.0 or later.
|
||
* The optional [*az* crate] dependency was updated to
|
||
[version 1.1][az-1-1].
|
||
* The following methods are now `const` functions:
|
||
* [`checked_neg`][f-cn-1-6], [`checked_add`][f-cad-1-6],
|
||
[`checked_sub`][f-cs-1-6], [`checked_mul_int`][f-cmi-1-6],
|
||
[`checked_shl`][f-cshl-1-6], [`checked_shr`][f-cshr-1-6],
|
||
[`checked_abs`][f-cab-1-6]
|
||
* The [`unwrapped_to_fixed`][f-utf-1-6] method was added to the
|
||
[`ToFixed`][f-tf-1-6] trait.
|
||
* The [`unwrapped_from_fixed`][f-uff-1-6] method was added to the
|
||
[`FromFixed`][f-ff-1-6] trait.

||
Version 1.5.0 (2020-11-05)
|
||
==========================
|
||
|
||
* The [`wide_mul`][f-wm-1-5] method was added to all fixed-point
|
||
numbers up to 64 bits wide ([issue 25]).
|
||
* Unwrapped methods for arithmetic together with the
|
||
[`Unwrapped`][unw-1-5] wrapper were added. Unwrapped methods panic
|
||
on overflow, even when debug assertions are disabled, similar to
|
||
how wrapping methods will wrap around even when debug assertions
|
||
are enabled. (This was previously an experimental feature
|
||
`unwrapped`.)
|
||
* The [`serde-str`][feat-1-5] feature was added. (This was
|
||
previously an experimental feature.)
|
||
* For the experimental feature [`num-traits`][feat-exp-1-5], some
|
||
missing supertraits were added to
|
||
[`FixedOptionalFeatures`][tfof-1-5].
|
||
* Bug fix: multiplication of [`FixedI128`][i128-1-5] was panicking
|
||
when multiplying some large negative numbers ([issue 26]).

||
Version 1.4.0 (2020-10-22)
|
||
==========================
|
||
|
||
* The following methods were added to all fixed-point types, to the
|
||
[`Fixed`][tf-1-4] trait, and to the [`Wrapping`][w-1-4] wrapper:
|
||
* [`recip`][f-rec-1-4], [`checked_recip`][f-crec-1-4],
|
||
[`saturating_recip`][f-srec-1-4],
|
||
[`wrapping_recip`][f-wrec-1-4],
|
||
[`overflowing_recip`][f-orec-1-4]
|
||
* For the experimental feature [`num-traits`][feat-exp-1-4], the
|
||
following traits were implemented where applicable ([issue 23]):
|
||
* [`Num`][nt-0-2-num]
|
||
* [`Signed`][nt-0-2-signed], [`Unsigned`][nt-0-2-unsigned]
|
||
* [`Inv`][nt-0-2-inv]
|
||
* [`MulAdd`][nt-0-2-ma], [`MulAddAssign`][nt-0-2-maa]
|
||
* [`FloatConst`][nt-0-2-fc]
|
||
* [`ToPrimitive`][nt-0-2-tp], [`FromPrimitive`][nt-0-2-fp]
|
||
* For the experimental feature [`serde-str`][feat-exp-1-4],
|
||
serialization in human-readable formats was made more convenient
|
||
to write manually ([issue 24]). This makes it incompatible with
|
||
the version in 1.3.0.

Version 1.3.0 (2020-10-15)
|
||
==========================
|
||
|
||
* The [`MulAssign`] implementation on fixed-point numbers now
|
||
accepts an rhs fixed-point number with a different number of
|
||
fractional bits from `self`.
|
||
* The following methods were added to all fixed-point types, to the
|
||
[`Fixed`][tf-1-3] trait, and to the [`Wrapping`][w-1-3] wrapper:
|
||
* [`mul_add`][f-ma-1-3], [`checked_mul_add`][f-cma-1-3],
|
||
[`saturating_mul_add`][f-sma-1-3],
|
||
[`wrapping_mul_add`][f-wma-1-3],
|
||
[`overflowing_mul_add`][f-oma-1-3]
|
||
* The new experimental feature [`unwrapped`][feat-exp-1-3] was
|
||
added, providing arithmetic methods that panic on overflow even
|
||
when debug assertions are disabled.
|
||
* The new experimental feature [`serde-str`][feat-exp-1-3] was
|
||
added, which makes serialization use the number’s value in
|
||
human-readable formats.

Version 1.2.0 (2020-09-02)
|
||
==========================
|
||
|
||
* The [`const_fixed_from_int!`][cffi-1-2] macro was added to make it
|
||
easy to define constant fixed-point numbers using integer
|
||
expressions ([issue 20]).

||
|
||
* The new experimental feature [`num-traits`][feat-nt-1-1] was added
|
||
to implement some traits, and to also add the relevant traits as
|
||
supertraits to the [`FixedOptionalFeatures`][fof-1-1] trait
|
||
([issue 18]).

|
||
|
||
* The crate now requires rustc version 1.34.0 or later.

||
* Parsing strings now rounds to the nearest with ties rounded to
|
||
even.
|
||
* Checked versions of string parsing methods are now available as

moved into the new `types::extra` module.
|
||
|
||
Version 0.4.2 (2019-08-16)
|

|
||
checked versions were added to all fixed-point numbers.
|
||
* The methods `from_fixed`, `to_fixed`, `from_int`, `to_int`,
|
||
`from_float`, and `to_float`, and their checked versions, were
|
||
deprecated.
|
||
* The new method `from_num` was added to the `Wrapping` wrapper.
|
||
* Bug fix: parsing of decimal fractions was fixed to give correctly
|
||
rounded results for long decimal fraction strings, for example
|
||
with four fractional bits, 0.96874999… (just below 31⁄32) and
|
||
0.96875 (31⁄32) are now parsed correctly as 0.9375 (15⁄16) and 1.0.

||
were added.
|
||
|
||
Version 0.4.0 (2019-08-08)
|
||
==========================
|
||
|
||
* The crate now requires rustc version 1.31.0 or later.
|
||
* The `traits` module was added, with its traits `Fixed`,
|
||
`FixedSigned`, `FixedUnsigned`, `FromFixed`, `ToFixed`,
|
||
`LossyFrom` and `LossyInto`.
|
||
* The `saturating_neg` method was added to all fixed-point numbers,
|
||
and the `saturating_abs` method was added to signed fixed-point
|
||
numbers.
|
||
* The `consts` module was added.
|
||
* The `signum` method now wraps instead of panics in release mode.
|
||
|
||
Incompatible changes
|
||
--------------------
|
||
|
||
* The sealed traits `Int` and `Float` now have no provided methods;
|
||
the methods in the old implementation are now provided by
|
||
`FromFixed` and `ToFixed`.
|
||
* Deprecated methods were removed.

|
||
|
||
Version 0.3.0 (2019-02-03)
|
||
==========================
|
||
|

|
||
removed.
|
||
* The new method `to_fixed` was added.
|
||

|
||
the `Int` trait.

|
||
`saturating_to_fixed`, `wrapping_to_fixed` and
|
||
`overflowing_to_fixed` were added to the `Float` trait.
|
||
* `PartialEq` and `PartialCmp` are now implemented for all
|
||
combinations of fixed-point numbers and primitive integers.
|
||
* The methods `int_bits` and `frac_bits` were deprecated and
|
||
replaced by the methods `int_nbits` and `frac_nbits`.
|
||
|
||
Version 0.2.1 (2019-01-29)
|
||
==========================
|
||
|
||
* Bug fix: the `from_fixed` and `from_int` methods (and their
|
||
checked counterparts) could return wrong values for negative
|
||
values.
|
||
* Bug fix: display was using one fractional digit less than
|
||
required, thus yielding the same output for diffent fixed-point
|
||
numbers.
|
||
|
||
Version 0.2.0 (2019-01-29)
|
||
==========================

|
||
`saturating_from_fixed`, `wrapping_from_fixed` and
|
||
`overflowing_from_fixed` were added.
|
||
* The new methods `checked_from_int`, `saturating_from_int`,
|
||
`wrapping_from_int` and `overflowing_from_int` were added.
|
||
* The new methods `from_float`, `checked_from_float`,

|
||
documented for negative values.

|
||
==========================
|
||
|
||
* `Unsigned` constants provided by the *typenum* crate are now used
|
||
for the number of fractional bits.
