Scientific numbers are + arbitrary precision and space efficient. They are represented using + <http://en.wikipedia.org/wiki/Scientific_notation scientific notation>. + The implementation uses a coefficient @c :: 'Integer'@ and a base-10 exponent + @e :: 'Int'@. A scientific number corresponds to the + 'Fractional' number: @'fromInteger' c * 10 '^^' e@. + . + Note that since we're using an 'Int' to represent the exponent these numbers + aren't truly arbitrary precision. I intend to change the type of the exponent + to 'Integer' in a future release. + . + The main application of 'Scientific' is to be used as the target of parsing + arbitrary precision numbers coming from an untrusted source. The advantages + over using 'Rational' for this are that: + . + * A 'Scientific' is more efficient to construct. Rational numbers need to be + constructed using '%' which has to compute the 'gcd' of the 'numerator' and + 'denominator'. + . + * 'Scientific' is safe against numbers with huge exponents. For example: + @1e1000000000 :: 'Rational'@ will fill up all space and crash your + program. Scientific works as expected: + . + >>> read "1e1000000000" :: Scientific + 1.0e1000000000 + . + * Also, the space usage of converting scientific numbers with huge exponents to + @'Integral's@ (like: 'Int') or @'RealFloat's@ (like: 'Double' or 'Float') + will always be bounded by the target type. + +homepage: https://github.com/basvandijk/scientific +bug-reports: https://github.com/basvandijk/scientific/issues +license: BSD3 +license-file: LICENSE +author: Bas van Dijk +maintainer: Bas van Dijk <v.dijk.bas@gmail.com> +category: Data +build-type: Simple +cabal-version: >=1.10 +extra-source-files: changelog +tested-with: + GHC ==7.6.3 + || ==7.8.4 + || ==7.10.3 + || ==8.0.2 + || ==8.2.2 + || ==8.4.4 + || ==8.6.5 + || ==8.8.4 + || ==8.10.7 + || ==9.0.2 + || ==9.2.6 + || ==9.4.4 + || ==9.6.1 + +source-repository head + type: git + location: git://github.com/basvandijk/scientific.git + +flag bytestring-builder + description: + Depend on the bytestring-builder package for backwards compatibility. + + default: False + manual: False + +flag integer-simple + description: Use the integer-simple package instead of integer-gmp + default: False + +library + exposed-modules: + Data.ByteString.Builder.Scientific + Data.Scientific + Data.Text.Lazy.Builder.Scientific + + other-modules: + GHC.Integer.Compat + Utils + + other-extensions: + BangPatterns + DeriveDataTypeable + Trustworthy + + ghc-options: -Wall + build-depends: + base >=4.5 && <4.19 + , binary >=0.5.1 && <0.9 + , containers >=0.4.2.1 && <0.7 + , deepseq >=1.3.0.0 && <1.5 + , hashable >=1.2.7.0 && <1.5 + , integer-logarithms >=1.0.3.1 && <1.1 + , primitive >=0.7.1.0 && <0.9 + , template-haskell >=2.8 && <2.21 + , text >=1.2.3.0 && <1.3 || >=2.0 && <2.1 + + if flag(bytestring-builder) + build-depends: + bytestring >=0.9 && <0.10.4 + , bytestring-builder >=0.10.4 && <0.11 + + else + build-depends: bytestring >=0.10.4 && <0.12 + + if impl(ghc >=9.0) + build-depends: base >=4.15 + + if flag(integer-simple) + build-depends: invalid-cabal-flag-settings <0 + + else + if flag(integer-simple) + build-depends: integer-simple + + else + build-depends: integer-gmp + + if impl(ghc <8) + other-extensions: TemplateHaskell + + if impl(ghc >= 9.0) + -- these flags may abort compilation with GHC-8.10 + -- https://gitlab.haskell.org/ghc/ghc/-/merge_requests/3295 + ghc-options: -Winferred-safe-imports -Wmissing-safe-haskell-mode + + hs-source-dirs: src + default-language: Haskell2010 + +test-suite test-scientific + type: exitcode-stdio-1.0 + hs-source-dirs: test + main-is: test.hs + default-language: Haskell2010 + ghc-options: -Wall + build-depends: + base + , binary + , QuickCheck >=2.14.2 + , scientific + , smallcheck >=1.0 + , tasty >=1.4.0.1 + , tasty-hunit >=0.8 + , tasty-quickcheck >=0.8 + , tasty-smallcheck >=0.2 + , text + + if flag(bytestring-builder) + build-depends: + bytestring + , bytestring-builder + + else + build-depends: bytestring + +benchmark bench-scientific + type: exitcode-stdio-1.0 + hs-source-dirs: bench + main-is: bench.hs + default-language: Haskell2010 + ghc-options: -O2 + build-depends: + base + , criterion >=0.5 + , scientific |
