Release notes

Version 1.7.3

  • Fix bugs and regressions involving EInteger's Pow, Root, and new Gcd

Version 1.7.2

  • Improve performance of EInteger's Gcd method for large integers

Version 1.7.1

  • Fix bugs in new char[] and byte[] overloads of FromString

Version 1.7.0

  • Added overloads to string-to-number methods that take char[] and byte[] arrays.
  • Added methods that convert EDecimal, EFloat, and ERational to and from raw bits that follow IEEE 754 binary floating-point formats (To/FromDoubleBits, To/FromSingleBits).
  • Added Log1P and ExpM1 methods to EDecimal and EFloat
  • Added 'long' overloads to several arithmetic methods
  • Added implication and equivalence (Imp/Eqv) methods and an nth-root method to EInteger

Version 1.6.0

  • Numerous performance improvements in the EInteger, EDecimal, EFloat, and ERational classes. Among them is the use of caches for small EInteger, EDecimal, and EFloat values, and faster multiplication algorithms for large EIntegers.
  • Correctness fixes to the Log() methods in EDecimal and EFloat
  • New LogN() method in EDecimal and EFloat
  • New methods in EInteger, including FromBytes, GetDigitCountAsEInteger, and DivRem(long)
  • New ToSizedEInteger/ToSizedEIntegerIfExact/IsInteger methods in EDecimal, EFloat, and ERational
  • New Create overloads in EFloat and ERational
  • New Min and Max methods in EInteger and ERational
  • Bug fixes

Version 1.5.1

  • Fix bugs in EDecimal.FromString and ERational.FromString involving substrings containing negative numbers.

Version 1.5.0

  • Major performance improvements in certain number parsing and generating methods, including the FromString methods of EInteger, EDecimal, EFloat, and ERational, and the ToEFloat method of EDecimal, especially where they take an arithmetic context (EContext) that specifies a limited precision and exponent range.
  • There were also performance improvements in digit count calculation and in rounding many-digit-long numbers.
  • Add int overloads to EDecimal.Pow and EFloat.Pow.
  • Add int overloads to several ERational methods.
  • Add CompareTo overloads and CompareToValue (which implements current CompareTo) in EDecimal, EFloat, and ERational. In a future version, CompareTo's behavior might change to CompareToTotal in each of these classes. Also certain CompareTo* methods now have consistent behavior when they receive a null argument.
  • ETrapException now has an Errors property that holds all errors that occur at the same time as the primary error.
  • Fixed edge cases when ToShortestString might return an incorrect result.
  • Fixed bug when some ETrapExceptions aren't thrown as they should.
  • Other bug fixes.

Version 1.4.3

  • Fix accuracy issue with Log, especially where 1 < x < 1.07
  • Remove StyleCop.Analyzers, which is used only in development, as dependency in .NET version

Version 1.4.2

  • Bug fix in the EInteger.CanFitInInt64 method

Version 1.4.1

  • Added EDecimals and EFloats classes to .NET 2.0 and .NET 4.0 versions; those classes were inadvertently omitted there

Version 1.4.0

  • Added EDecimals and EFloats class that implements more methods for arbitrary-precision decimal and binary numbers
  • Increment and decrement operators added to EInteger, EDecimal, EFloat, and ERational classes
  • Allowed EDecimal values in (-1, 0) to EDecimal's *Checked methods, to conform to documentation.
  • Added WithNoFlagsOrTraps method and HasFlagsOrTraps property to EContext
  • Add Mod(int), Pow(int), and FromBoolean methods to EInteger
  • Add And, Not, Xor, and Or methods to EInteger.cs
  • Add Copy method to EDecimal, EFloat, and ERational
  • Add CompareToTotalMagnitude overload to EDecimal, EFloat, and ERational
  • Deprecated Odd and ZeroFiveUp rounding modes
  • Bug fixes and performance improvements

  • Add EInteger overloads to EInteger.GetSignedBit, EInteger.GetUnsignedBit, EInteger.ShiftLeft, and EInteger.ShiftRight
  • Add GetDigitCountAsEInteger and GetSignedBitLengthAsEInteger methods to EInteger class
  • Check for overflow in GetLowBit, GetDigitCount, GetUnsignedBitLength, and GetSignedBitLength methods in EInteger class; deprecate those methods
  • Add FromBoolean methods to EDecimal, EFloat, and ERational

Version 1.2.2:

  • Fixed referencing issues with minor version 1.2.1

Version 1.2.1:

  • Fixed bugs with new EInteger.Add and EInteger.Subtract overloads

Version 1.1.1

  • Numbers .NET 2.0 assembly had wrong version number.

Version 1.1.0
