#12642: Float parser slow without float.h

 Reporter:  mihai.babiac@…        |      Owner:  djowel
     Type:  Bugs                  |     Status:  new
Milestone:  To Be Determined      |  Component:  spirit
  Version:  Boost 1.61.0          |   Severity:  Optimization
 Keywords:  float float.h cfloat  |
----------------------------------+--------------------------
 The scaling function for the float/double parser has a fast specialization
 which is only enabled if the doubles respect standard  IEEE-754. This is
 checked through the preprocessor macro DBL_MAX_10_EXP which is defined in
 float.h. I think this file should be included in the header or this should
 at least be mentioned in the docs.
