+
+Sun Mar 6 19:52:22 2005 Ben Pfaff <blp@gnu.org>
+

+
+ * data-in.c: (apply_implied_decimals) New function.
+ (parse_numeric) Don't adjust exponent if DI_IMPLIED_DECIMALS not

+Sun Mar 6 17:07:20 2005 Ben Pfaff <blp@gnu.org>
+
+ When the lexer sees something like `-5' in the input, it has to
+ decide whether it's a negative numeric constant token or a '-'
+ token followed by a positive numeric constant token. It always
+ decides on the former, and then the parser can call
+ lex_negative_to_dash() if it wants the latter. However, this
+ doesn't work for the case of `-0', because negative zero is
+ (portably) indistinguishable from positive zero. So now we divide
+ T_NUM into two tokens, T_POS_NUM and T_NEG_NUM, to make the
+ distinction clear. This requires a little bit of extra effort,
+ because there were several references to T_NUM in the code base.
+
+ * lexer.c: (lex_get) Use T_NEG_NUM and T_POS_NUM to distinguish
+ positive and negative numeric constants.
+ (lex_double_p) Renamed lex_is_number(). Changed return type to
+ bool. Updated all relevant references to T_NUM to instead use
