[1.11.0] - 2022-02-13

Added

NewType gives access to all types this library can handle.
ToComparable and FromComparable
- You can compare such values without decoding.
- You can find the difference relying on unsigned integer overflow.

[1.10.0] - 2022-01-12

Added

Integer overflow protection in UseIntegerDelta.

Changed

It is faster than v1.9.0.
The source code is shorter, clearer and commented in detail.

[1.9.0] - 2022-01-09

Added

Methods Abs(x), MinValue(), MaxValue().

Changed

It is 28% faster.

[1.8.0] - 2022-01-05

Added

Support for 2-bit exponent.

Removed

All preconfigured methods.

[1.7.0] - 2022-01-05

Changed

Tests now work through the new API.
Single-module package.

[1.6.0] - 2022-01-04

Added

Fully customizable object-oriented API.

Deprecated

All preconfigured methods.

[1.5.0] - 2022-01-01

Removed

Default, 14 and m11x3 types.

Changed

Type defaultD is now 12.
Type unsigned renamed to 12u.
Type 14d renamed to 14.
Type m11x3d renamed to 15x3.

[1.4.0] - 2022-01-01

Changed

EncodeDelta[TypeName] renamed to GetIntegerDelta[TypeName].
DecodeDelta[TypeName] renamed to UseIntegerDelta[TypeName].

[1.3.1] - 2022-01-01

Changed

Even though everything works fine, I've added an explicit limit on the maximum value of the mantissa to ensure that it never gets rounded incorrectly.

[1.3.0] - 2022-01-01

Deprecated

Default, 14 and m11x3 types.

[1.2.0] - 2022-01-01

Added

New types defaultD, 14d, m11x3d with different bits ordering suitable for delta encoding.
Functions EncodeDelta[TypeName], DecodeDelta[TypeName].

Changed

Accuracy has increased. The mantissa – binarySignificand variable – is now rounded to the nearest integer (git:18cfb1a9).
Function getExponent has been changed to match the rounding change (git:28458380).

[1.1.0] - 2021-12-25

Added

15-bit type with 3-bit exponent (m11x3).
