@ -9,12 +9,12 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
|

### Changed
|
||||
|
||||
- X1OD: `IBinaryInteger<T>.Factorial` now starts at `IBinaryInteger<T>.MultiplicativeIdentity` not
|
||||
`IBinaryInteger<T>.One`.
|
||||
- X10D: Removed `byte.Product`, `short.Product`, `ushort.Product`, `int.Product`, `uint.Product`, `long.Product`,
|
||||
and `ulong.Product`, in favour of `INumber<T>.Product`.
|
||||
- X10D: Removed `byte.RangeTo`, `short.RangeTo`, `ushort.RangeTo`, `int.RangeTo`, `uint.RangeTo`, `long.RangeTo`,
|
||||
and `ulong.RangeTo`, in favour of `INumber<T>.RangeTo`.
|
||||
- X10D: Removed `IEnumerable<T>.GreatestCommonFactor` for all integer types in favour of generic math.
|
||||
- X10D: Removed `IEnumerable<T>.LowestCommonMultiple` for all integer types in favour of generic math.
|
||||
- X10D: Removed `IEnumerable<T>.Product` for all integer types in favour of generic math.
|
||||
- X10D: Removed `IEnumerable<T>.RangeTo` for all integer types in favour of generic math.
|
||||
- X10D: Removed `T.Sign` for all numeric types in favour of generic math.
|
||||
- X10D: Removed `T.Wrap` for all numeric types in favour of generic math.
