ruby--ruby/include/ruby/ruby.h
ko1 25c0cb981a * include/ruby/ruby.h: introduce 2 macros: 
RFLOAT_VALUE(v), DOUBLE2NUM(dbl).
  Rename RFloat#value -> RFloat#double_value.
  Do not touch RFloat#double_value directly.
* bignum.c, insns.def, marshal.c, math.c, numeric.c, object.c,
  pack.c, parse.y, process.c, random.c, sprintf.c, string.c,
  time.c: apply above changes.
* ext/dl/mkcallback.rb, ext/json/ext/generator/generator.c:
  ditto.
