v0.3.0-alpha

Added

• Single precision support for all methods.
• Exception interface:
  • Alea::NoConvergeError
  • Alea::UndefinedError
  • Alea::InfinityError
  • Alea::NaNError
• Spec interface with macros to simplify testing:
  • arg_test
  • sanity_test
  • param_test
  • dist_test
• Alea::Random:
  • all standard sampling methods now accepts any-typed values.
  • Poisson distribution support.
• Alea::XSR128, Alea::XSR256:
  • UInt32 generation capabilities.
  • new now accepts initial states (32/64 bits) as StaticArray.
  • new now accepts initial seeds (32/64 bits) as Int.
  • #jump_* methods to advance states.
• Alea::CDF:
  • all cdf methods now accepts any-typed values.
  • Poisson distribution support.
  • ChiSquare distribution support.
  • Gamma distribution support.
• Modules:
  • Alea::Core to store internal implementations.
  • Alea::Core::SpecFun to store special functions implementations.
  • Alea::Core::SpecFun::Gamma for special gamma functions.
• Engines:
  • Alea::Core::SplitMix64(N) struct for state64 initializations.
  • Alea::Core::Mulberry32(N) struct for state32 initializations.

Changed

• Alea::Random is now a struct.
• Renamed all occurences of chi_square into chisq.
• Renamed all occurences of exponential into exp.
• Renamed all occurences of mean into loc.
• Renamed all occurences of freedom into df.
• Renamed initstate into proper seed in Alea::Random.new.
• Alea::CDF.chisq* have no more default df.
• #next_u, #next_f are deprecated. Now they have bit-fixed names:
  • #next_u32 : UInt32
  • #next_u64 : UInt64
  • #next_f32 : Float32
  • #next_f64 : Float64
• #jump in Alea::Random is deprecated. Use jump method directly
  from Alea::Random#prng instead.
• Unparsed sampling methods (e.g.: #next_gamma) now have specific
  types for arguments.

Fixed

• A bug causing splitmix to generate bad values.
