Version 1.0.1

• Really strong-name sign the assembly, which (probably) was inadvertently delay-signed in version 1.0.

Version 1.0

• Filled out documentation so that there are no more undocumented parts

Version 0.5

• Moved from .NET Portable to .NET Standard 1.0. Contributed by GitHub user NZSmartie
• Broke backwards compatibility with .NET Framework 4.0
• Bug fixes

Version 0.4:

• Assembly signed with a strong name
• Some improvements to documentation

Version 0.3:

• Deprecated ERational constructor
• Added many type conversion operators and methods to EDecimal, EFloat, ERational, and EInteger
• Added FromString, CompareToTotal, and CompareToTotalMagnitude methods to ERational
• An overload of RoundToExponentExact in EDecimal is no longer obsolete and uses the rounding mode specified
• Used a new division implementation in EInteger
• Used the new division implementation to optimize conversion of huge EIntegers to decimal strings
• Bug fixes

Version 0.2.2:

• Previous assembly was released with wrong version number

Version 0.2.1:

• Fixed corner cases in EFloat's ToSingle and ToDouble methods

Version 0.2:

• Performance improvements

• Renamed several methods in EDecimal and EFloat
• RoundToIntegral* methods renamed to RoundToInteger* methods
• Renamed some EInteger integer conversion methods; added CanFitInInt64, GetUnsignedBitLengthAsEInteger, and GetLowBitAsEInteger methods
• Several operators added to EDecimal in C# version
• Rewrote code that converts from decimal to binary floating-point; add ToEFloat method taking an EContext in EDecimal
• Added ToShortestString method in EFloat
• Add UnlimitedHalfEven EContext object
