2005-09-25Fix wrong normalization in compare. From andreas@Otto Moerbeek
2005-04-02- Fix raise for negative exponents (noted by naddy@)Otto Moerbeek
- Fix wrong scale for mantissa < 1.
2005-03-29Nicer wrapping. We used to mimick the old dc(1), which printsOtto Moerbeek
...\<newline><newline> in some cases. ok deraadt@
2005-03-28Linefeed is part of a line according to POSIX, so take that into accountOtto Moerbeek
when computing line wraps. ok deraadt@

2005-03-27Use inclusive bound check for line length, it is more clear.Otto Moerbeek
2005-03-27Make call stack auto-growing, instead of fixed size. Enables much deeperOtto Moerbeek
recursion.
2005-03-15snprintf(buf, sizeof(buf), "%s", p) is silly, use strlcpy(). From Bruno Rohee.Otto Moerbeek
2004-12-01use volatile sig_atomic_t for vars set in signal handlers. spotted by deraadt@Otto Moerbeek
2004-12-01Fix stop condition for sqrt. Due to the fact that we're doing NewtonOtto Moerbeek
iteration with intgeres, the stop condition is reached if x_n == x_n+1, or the difference is one, but only stop if that is hit a second time. Avoids looping with difference 1,-1,1,-1... Problem spotted by Paul de Weerd. Regress tested against 4.2BSD dc(1) and GNU dc(1).
2004-10-18Implement command line evaluation of expressions by implementing the -e option.Otto Moerbeek

2003-12-19Do something sensible on ^C: unwind stack and be ready for new input.Otto Moerbeek
2003-12-02Fix a max recursion off-by-one.Otto Moerbeek
2003-12-01Allow for more registers using a 2 byte index. This feature isOtto Moerbeek
enabled by supplying the -x option on the command line. Allows long variable names in bc(1) (to appear soon). If no -x option is given, behave exactly as before. ok jmc@

2003-11-26Avoid a core dump on reading uninitiazed array locations.Otto Moerbeek
2003-11-17A basic stack operation that is missing from the original dc (andOtto Moerbeek
GNU dc as well): drop ('R').
2003-11-14Implement new boolean operations 'N' (not), 'G' (equals), '(' (less)Otto Moerbeek
and '{' (less or equal). These operations push their result back to the stack. Used by soon to appear boolean operations in bc(1). man page tweaks and ok jmc@
2003-11-14The BN_add_word() bug has been squashed, so we don't need a workaroundOtto Moerbeek
any more.

2003-10-22Implement extended comparison operators, to allow for an if ... else constructOtto Moerbeek

2003-10-18Describe new J and M operators. Also some small cleanup.Otto Moerbeek
2003-10-18o Implement new J (jump) and M (mark) operators. The J operatorOtto Moerbeek
pops n recursion levels and then skips to the first occurence of the M operator. These operators are used to implement the "continue" statement in bc(1). o Ifdef debug code.

2003-09-30Teach dc(1) how to read strings with unbalanced braces by introducingOtto Moerbeek
backslash as an escape char. This is needed for bc(1), which is required by Posix to handle strings with brackets in them.
