* usr.bin/bc: remove OpenBSD derived bc and dc commandsStefan Eßer2024-11-241-1773/+0
| | | | | | | | | | | | | | | | | | | | | | | | In 2020, an improved implementation of the bc and dc commands developed by Gavin D. Howard has been imported into FreeBSD. It has replaced the OpenBSD-derived versions of these commands in all currently supported FreeBSD releases. The OpenBSD versions could still be built using the WITHOUT_GH_BC option. There have been no reports of problems or unexpected deviations from the OpenBSD version for some time, therefore keeping the OpenBSD version is no longer required in FreeBSD. This commit removes the option to build the OpenBSD version and corresponding source files from -CURRENT. No MFC is planned, all currently released FreeBSD versions should retain the build option. The WITHOUT_GH_BC option is no longer accepted and will cause make buildworld to fail.

* dc(1): fix modulo operations with fractional inputsAlan Somers2017-12-071-10/+29
| | | | | | | | | | | | | | Our dc(1) has never correctly calculated remainders with fractional inputs. Both bmod and bdivmod seem to have copy/pasted code from bdiv, which results in the remainder having the wrong output scale.

* dc(1): fix input of non-decimal fractional numbersAlan Somers2017-12-051-25/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | Inputting fractional non-decimal numbers has never worked correctly in our OpenBSD-derived dc(1). It truncates the input to a number of decimal places equal to the number of hexadecimal (or whatever base) places given on the input. That's unacceptable, because many numbers require more precision to represent in base 10 than in their original bases. Fix this bug by using as many decimal places as needed to represent the input, up to the maximum of the global scale factor. This has one mildly surprising side effect: the scale of a number entered in non-decimal mode will no longer necessarily equal the number of hexadecimal (or whatever base) places given on the input. I think that's an acceptable behavior change, given that inputting fractional non-decimal numbers never worked in the first place, and the man page doesn't specify whether trailing zeros on the input should affect a number's scale.
