Eliminate all of the redundant conformance constraints in the standard
library that were identified by the newly-introduced warning for
redundant, explicitly-specified conformances.
- CYGWIN symbol is used to distinguish Cygwin environment from other OS
and other environment in Windows.
- Added windows and windowsCygnus to OSVersion in StdlibUnittest
The result of these methods was incorrectly documented as having
the same sign as `other` (the divisor) rather than `self` (the
dividend). This patch corrects the documentation, and also fixes
the capitalization of `formTruncatingRemainder` in one location.
Replace the non-generic tgmath functions with generic <T: FloatingPoint> implementations where possible, and move the global sqrt() operation into tgmath.
* [stdlib] Introducing the new Arithmetic protocol
* [stdlib] conforming floating point types to the new Arithmetic protocol
* [stdlib] removing AbsoluteValuable conformance from floating point types
* [stdlib] removing the integers prototype
change includes both the necessary protocol updates and the deprecation
warnings
suitable for migration. A future patch will remove the renamings and
make this
a hard error.
Implemented SE-0113 + residual SE-0067 operations.
- adds `rounded` and `round` to `FloatingPoint`, from SE-0113.
- adds `remainder`, `squareRoot`, and `addingProduct`, from SE-0067.
- adds basic test coverage for all of the above.
- provides a default implementation of `nextDown` on `FloatingPoint`.
* Bring the behavior of Self.minimum, .maximum, .minimumMagnitude and .maximumMagnitude in line with the IEEE 754 rules.
Specifically, if either argument is a signaling NaN, the result should be a quiet NaN. Previously, signaling NaN inputs were treated identically to quiet NaN inputs.
Some other changes folded in with this:
- Formally define which argument is returned if lhs == rhs or abs(lhs) == abs(rhs) in the case of the Magnitude versions. This guarantees that the set {min,max} is identitical to the set {lhs,rhs} so long as neither argument is NaN. This is not only a nod to formalism; it's also a critical property for generic head-tail arithmetic to simulate wider types.
- Added test coverage for these four operations.
