      Make the Lisp reader and string-to-float more consistent. · 8b9587d7
      Paul Eggert authored
      * data.c (atof): Remove decl; no longer used or needed.
      (Fstring_to_number): Use new string_to_float function, to be
      consistent with how the Lisp reader treats infinities and NaNs.
      Do not assume that floating-point numbers represent EMACS_INT
      without losing information; this is not true on most 64-bit hosts.
      Avoid double-rounding errors, by insisting on integers when
      parsing non-base-10 numbers, as the documentation specifies.
      Report integer overflow instead of silently converting to
      integers.
      * lisp.h (string_to_float): New decl, replacing ...
      (isfloat_string): Remove.
      * lread.c (read1): Do not accept +. and -. as integers; this
      appears to have been a coding error.  Similarly, do not accept
      strings like +-1e0 as floating point numbers.  Do not report
      overflow for some integer overflows and not others; instead,
      report them all.  Break out the floating-point parsing into a new
      function string_to_float, so that Fstring_to_number parses
      floating point numbers consistently with the Lisp reader.
      (string_to_float): New function, replacing isfloat_string.
      This function checks for valid syntax and produces the resulting
      Lisp float number too.
