Data.Scientific provides a space efficient and arbitrary precision
scientific number type.

Scientific numbers are represented using scientific notation. It uses a
coefficient c :: Integer and a base-10 exponent e :: Int (do note that
since we're using an Int to represent the exponent these numbers aren't
truly arbitrary precision). A scientific number corresponds to the
Fractional number: fromInteger c * 10 ^^ e.
Update to 0.3.3.0 changelog: 0.3.3.0 * Add the isFloating or isInteger predicates. Courtesy of Zejun Wu (@watashi). * Add the toRealFloat' and toBoundedInteger functions. Courtesy of Fujimura Daisuke (@fujimura). 0.3.2.2 * Enable package to link with integer-simple instead of integer-gmp using the -finteger-simple cabal flag. Courtesy of @k0ral. 0.3.2.1 * Parameterize inclusion of the Data.ByteString.Builder.Scientific module using the bytestring-builder flag. Disabling this flag allows building on GHC-7.0.4 which has bytestring-0.9 installed by default. 0.3.2.0 * Add the floatingOrInteger function * Fix build on GHC-7.0.4 * More efficient and better behaving magnitude computation * Lower the number of cached magnitudes to 324 (same as GHC.Float) 0.3.1.0 * Don't normalize on construction but do it when pretty-printing instead. Also provide a manual normalize function. * Improve efficiency of toRealFloat * Added note about caching magnitudes * Dropped dependency on arithmoi * Make benchmark easier to build * Add junit XML output support (for Jenkins) 0.3.0.2 * Lower the minimal QuickCheck version. * Make sure sized exponents are generated in the QuickCheck tests. 0.3.0.1 * Fix build for bytestring-0.10.0.* 0.3.0.0 * Fix a DoS vulnerability that allowed an attacker to crash the process by sending a scientific with a huge exponent like 1e1000000000. * Fix various RealFrac methods. * Cache some powers of 10 to speed up the magnitude computation. * Normalize scientific numbers on construction. * Move the Text Builder to its own module & provide a ByteString builder * Added more documentation 2014-08-16 23:54:50 +02:00			`Data.Scientific provides a space efficient and arbitrary precision`

Import scientific-0.2.0.2 as math/hs-scientific, packaged for wip. A Scientific number is an arbitrary-precision floating-point number represented using scientific notation. A scientific number with coefficient c and base10Exponent e corresponds to the Fractional number: fromInteger c * 10 ^^ e Its primary use-case is to serve as the target of parsing floating point numbers. Since the textual representation of floating point numbers use scientific notation they can be efficiently parsed to a Scientific number. 2014-05-31 23:31:57 +02:00
