v2.1.1

Added

• RandomProvider: A provider to supply random numbers.
  • randomInt(): Supplies a random integer.
  • randomDecimal(): Supplies a random decimal between 0 and 1 (inclusive)
  • randomReal(): Supplies a random real number.

Changed

• Composer: Removed dependency on ircmaxell/random-lib, as it was outdated and is now replaced with Fermat's RandomProvider.

v2.1.0

Added

• NumberCollection: Added the method selectScale() to return the int value of the largest scale among all collection members.

v2.0.1

Fixed

• Composer: Fixed an issue with dependencies that created errors for libraries which include this as a dependency.

Removed

• Composer:

    • ext-stats: * (As this library is no longer maintained and unavailable on PHP 7+, it is being removed)
• Providers:
  • SequenceProvider
    • Removed empty nthSecTanCoefNumber function until an implementation exists

Changed

• Providers:
  • Distributions:
    • Removed references to ext-stats in all distributions
    • Fixed missing @throws in docblocks in all distributions
    • Now extend Distribution abstract class
    • Use the randomInt() method in PolyfillProvider instead of RandomLib directly
  • SequenceProvider:
    • Allowed nthEvenNumber(), nthOddNumber(), nthPowerNegativeOne(), nthEulerZigzag(), and nthFibonacciNumber() to return windows of the sequence as a NumberCollection object
• Types:
  • Base:
    • Interfaces:
      • ALL: Changed namespace from Samsara\Fermat\Types\Base to Samsara\Fermat\Types\Base\Interfaces
      • DecimalInterface:
        • Changed signature of log10() and ln() to $scale = null instead of $scale = 10
        • Changed type of $scale parameter in log10() and ln() from int to int|null
      • NumberInterface:
        • Moved the convertToBase() method to the new BaseConversionInterface
    • Traits:
      • ArithmeticTrait:
        • Updated all arithmetic functions to work with imaginary numbers, complex numbers, and negative numbers (square root)
    • Number:
      • Changed namespace from Samsara\Fermat\Types to Samsara\Fermat\Types\Base
      • Moved many methods into traits
      • Now passes the scale setting to ALL calls to ArithmeticProvider allowing scale up to 2147483646 digits.

Fixed

• Providers:
  • Distributions:
    • Exponential:

    • LogTrait:
      • Fixed $scale to work the way it does in other functions for log10() and ln()
