synopsis:            Numbers represented using scientific notation
description:
  @Data.Scientific@ provides a space efficient and arbitrary precision
  scientific number type.
  .
  'Scientific' numbers are represented using
  <http://en.wikipedia.org/wiki/Scientific_notation 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@.
  .
  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 numbers only need to be normalized, i.e. @10000000@
  to @1e7@.
  .
  * '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.
