-- | C99 printf "%a" style formatting and parsing
--   
--   Format and parse floating point values as C99 printf/scanf with format
--   string %a do
@package float-binstring
@version 0.1


-- | This module contains functions for formatting and parsing floating
--   point values as C99 printf/scanf functions with format string
--   <tt>%a</tt> do.
--   
--   Format is [-]0x<i>h.hhhhh</i>p±<i>ddd</i>, where <i>h.hhhhh</i> is
--   significand as a hexadecimal floating-point number and <i>±ddd</i> is
--   exponent as a decimal number. Significand has as many digits as needed
--   to exactly represent the value, fractional part may be ommitted.
--   
--   Infinity and NaN are represented as <tt>±inf</tt> and <tt>nan</tt>
--   accordingly.
--   
--   For example, <tt>(π ∷ Double) = 0x1.921fb54442d18p+1</tt>.
--   
--   Assertion
--   
--   <pre>
--   Just x ≡ readFloatStr (showFloatStr x)
--   </pre>
--   
--   holds (modulo bugs and cosmic rays).
--   
--   Floating point radix is assumed to be 2.
