Changelog for arithmoi- Switch to smallcheck 1.1.3. This release supports GHC 7.8, 7.10, 8.0 and 8.2. Breaking changes: 'Math.NumberTheory.Moduli' was split into 'Math.NumberTheory.Moduli.{Chinese,Class,Jacobi,Sqrt}'. Functions 'jacobi' and 'jacobi'' return 'JacobiSymbol' instead of 'Int'. Functions 'invertMod', 'powerMod' and 'powerModInteger' were removed, as well as their unchecked counterparts. Use new interface to modular computations, provided by 'Math.NumberTheory.Moduli.Class'. New functions: Brand new 'Math.NumberTheory.Moduli.Class' (#56), providing flexible and type safe modular arithmetic. Due to use of GMP built-ins it is also significantly faster. New function 'divisorsList', which is lazier than 'divisors' and does not require 'Ord' constraint (#64). Thus, it can be used for 'GaussianInteger'. Improvements: Speed up factorisation over elliptic curve up to 15x (#65). Polymorphic 'fibonacci' and 'lucas' functions, which previously were restricted to 'Integer' only (#63). This is especially useful for modular computations, e. g., 'map fibonacci [1..10] :: [Mod 7]'. Make 'totientSum' more robust and idiomatic (#58). Switch to QuickCheck 2.10. This release supports GHC 7.8, 7.10 and 8.0. GHC 7.6 is no longer supported. Breaking changes: Remove deprecated interface to arithmetic functions (divisors, tau, sigma, totient, jordan, moebius, liouville, smallOmega, bigOmega, carmichael, expMangoldt). New interface is exposed via Math.NumberTheory.ArithmeticFunctions (#30). Deprecate integerPower and integerWordPower from Math.NumberTheory.Powers.Integer. Use (^) instead (#51). Math.NumberTheory.Logarithms has been moved to the separate package integer-logarithms (#51). Rename Math.NumberTheory.Lucas to Math.NumberTheory.Recurrencies.Linear. New functions: Add basic combinatorial sequences: binomial coefficients, Stirling numbers of both kinds, Eulerian numbers of both kinds, Bernoulli numbers (#39). E. g., > take 10 $ Math.NumberTheory.Recurrencies.Bilinear.bernoulli [1 % 1,(-1) % 2,1 % 6,0 % 1,(-1) % 30,0 % 1,1 % 42,0 % 1,(-1) % 30,0 % 1] Add the Riemann zeta function on non-negative integer arguments (#44). E. g., > take 5 $ Math.NumberTheory.Zeta.zetas 1e-15 [-0.5,Infinity,1.6449340668482262,1.2020569031595945,1.0823232337111381] Improvements: Speed up isPrime twice; rework millerRabinV and isStrongFermatPP (#22, #25). This release supports GHC 7.6, 7.8, 7.10 and 8.0. Add Math.NumberTheory.ArithmeticFunctions with brand-new machinery for arithmetic functions: divisors, tau, sigma, totient, jordan, moebius, liouville, smallOmega, bigOmega, carmichael, expMangoldt (#30). Old implementations (exposed via Math.NumberTheory.Primes.Factorisation and Math.NumberTheory.Powers.Integer) are deprecated and will be removed in the next major release. Add Karatsuba sqrt algorithm, improving performance on large integers (#6). Fix incorrect indexing of FactorSieve (#35). This release supports GHC 7.6, 7.8, 7.10 and 8.0. Add new cabal flag check-bounds, which replaces all unsafe array functions with safe ones. Add basic functions on Gaussian integers. Add Moebius mu-function. Forbid non-positive moduli in Math.NumberTheory.Moduli. Fix out-of-bounds error in Math.NumberTheory.Primes.Heap, Math.NumberTheory.Primes.Sieve and Math.NumberTheory.MoebiusInversion. Fix 32-bit build. Fix binaryGCD on negative numbers. Fix highestPower (various issues). Add integerLog10 variants at Bas van Dijk's request and expose Math.NumberTheory.Powers.Integer, with an added integerWordPower. Update for GHC-7.8, the type of some primops changed, they return Int# now instead of Bool. Fixed bugs in modular square roots and factorisation. Relaxed dependencies on mtl and containers Fixed warnings from GHC-7.5, Word(..) moved to GHC.Types Removed SPECIALISE pragma from inline function (warning from 7.5, probably pointless anyway) Sped up factor sieves. They need more space now, but the speedup is worth it, IMO. Raised spec-constr limit in MoebiusInversion.Int Fixed Haddock bug Added generalised Moebius inversion, to be continued Added modular square roots and Chinese remainder theorem Performance tweaks for powerModInteger (~10%) and invertMod (~25%). Fix bug in psieveFrom Fix bug in nthPrime Fix bug in powerMod Relax bounds on array dependency for 7.4.* Fix copy-pasto (only relevant for 7.3.*) Fix imports for ghc >= 7.3 Added certificates and certified testing/factorisation Fixed doc bugs Elaborate on overflow, work more on native Ints in Eratosthenes First release
