haskell 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. Provide the Data.ByteString.Builder.Scientific module (requires bytestring >= 0.10). basvandijk/scientific
