+
+ * expressions/helpers.c: (struct func_params) Removed.
+ (generalized_idf) Removed.
+ (cdf_beta) Removed.
+ (idf_beta) Removed.
+ (idf_fdist) Use gslextras_cdf_beta_Pinv() instead of idf_beta().

+
+Sun Mar 6 23:25:40 2005 Ben Pfaff <blp@gnu.org>
+
+ * data-in.c: Use `bool' throughout, where relevant.
+
+Sun Mar 6 19:52:22 2005 Ben Pfaff <blp@gnu.org>
+
+ DATA LIST with free-field formats should not have implied decimal
+ places (bug #12035). Also clean up data-in.c a bit.
+
+ * data-in.h: (enum) Add DI_IMPLIED_DECIMALS.
+
+ * data-in.c: (apply_implied_decimals) New function.
+ (parse_numeric) Don't adjust exponent if DI_IMPLIED_DECIMALS not
+ set. Also, get rid of gotos.
+ (parse_Z) Use apply_implied_decimals() if the field doesn't
+ contain a decimal point.
+ (parse_N) Use apply_implied_decimals().
+ (parse_IB) Ditto.
+ (parse_PIB) Ditto.
+ (parse_P) Ditto.
+ (parse_PK) Ditto.
+ (to_roman) Removed.
+ (parse_enum) New function.
+ (macro CHAR_IS_ROMAN) Removed.

+
+ 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
+ this function.
+ (lex_double) Renamed lex_number(). All references updated.
+ (lex_integer_p) Renamed lex_is_integer(). Changed return type to
+ bool. All references updated.
+ (lex_token_representation) Understand T_NEG_NUM and T_POS_NUM.
+ (lex_negative_to_dash) Ditto.
+ (dump_token) Ditto.
+
+ * lexer.h: (enum) Add T_POS_NUM, T_NEG_NUM. Remove T_NUM.

+
+ * expressions/operations.def: (VEC_ELEM_NUM) Treat user-missing
+ values as system-missing.

+
+ * expressions/optimize.c: (optimize_tree) Fix optimization bug for
+ x**2.
+
+ * expressions/parse.c: (type_coercion_core) Set *node to NULL on
+ failure, as indicated by function comment.
+ (parse_binary_operators) Always return NULL on type_coercion()
+ failure. Should have been doing this anyway, but bug in
+ type_coercion_core() filtered through.
+ (parse_add) Fix typo in user message.
+ (parse_primary) Understand T_NEG_NUM and T_POS_NUM.
+
+Sun Mar 6 10:47:13 2005 Ben Pfaff <blp@gnu.org>
+
+ * expressions/operations.def: Add VALUE function.
+

+
+ * expressions/PSPP_expressions.pm: Renamed it back to generate.pl
+ but fixed the real problem that was preventing the build from a
+ separate directory. I liked it my way better ;-)
+
+Thu Mar 3 23:17:51 2005 Ben Pfaff <blp@gnu.org>
+
+ * expressions/parse.c: (expr_parse) Fix parameter type. Thanks to

+ * expressions/Makefile.am expressions/evaluate.h.pl
+ expressions/evaluate.inc.pl expressions/operations.h.pl
+ expressions/optimize.inc.pl expressions/parse.inc.p:
+
+ Renamed generate.pl to PSPP_expressions.pm and adjusted *.pl
+ to suit.
+
+ Fixed everything so that it can be built from an arbitrary
