Bug fixes

Added tie-breaking exponentiation operator implementations for concrete integer types in the standard library.

Exponentiation operators

• Added the exponentiation operator ** and the compound assignment operator **=.
• Deprecated BinaryInteger.pow(_:_:) and Math.pow(_:_:).

CocoaPods

Added a PodSpec file (and a .swift-version file) for CocoaPods support.

Bug fixes

Worked around a compiler segmentation fault by assuming memory bound instead of binding memory.

Bug fixes and documentation improvements

• Updated doc comments.
• Updated generic algorithms for revised integer protocols.

Bug fixes

• Removed Complex.isCanonical and Complex.polar.
• Fixed implementation of Complex.isNaN and Complex.isSignalingNaN to align with C/C++ standards: a complex value is NaN if at least one of its components is NaN and the other is not infinite.
• Fixed implementation of Complex multiplication and division to align handling of special values with C/C++ standards.
• Fixed implementation of Complex.tanh(_:) to align handling of special values with C/C++ standards.
• Refined implementation of Complex.description for values with a negative imaginary component.
• Fixed implementation of Rational initializers that convert from a BinaryFloatingPoint value.

Bug fixes

Fixed implementation of Rational.isProper.

Integer square root and cube root

• Added integer square root and cube root functions.
• Removed power(of:) requirement from Math, substituting pow(_:_:) (formerly an extension method).

Bug fixes

• Expanded tests.
• Fixed implementation of certain default implementations for protocol requirements of Math and Real.

Codable

Conformed Complex and Rational to Codable.
