b1d16c979a Removed obsolete version of Int36 (using signed integers internally); sticking with unsigned integers internally not only simplifies some of the existing logic, but will make it easier to add logical operations later (eg, AND, OR, XOR, etc) 2017-02-18 09:36:47 -08:00

acdf89ec54 Make Int36 toDecimal() more paranoid (we want perfect output, or no output at all) 2017-02-18 09:28:43 -08:00

688fa635c8 Clarified the operation of negate(), added an explicit extend(), and made toDecimal() more robust (in case we end up with goofy values) 2017-02-17 11:52:36 -08:00

6bc0d8ac49 Trying a second approach to the Int36 class that sticks to unsigned numbers internally (only downside so far is that the detecting arithmetic overflow/underflow is more work and hasn't been implemented yet) 2017-02-15 16:16:32 -08:00

8f0b808b1e Switching to machine XML files that use a machine 'type' attribute rather than 'class'; 'class' can still be used to specify the machine type if 'type' is omitted, but going forward, it should only be used to specify an alternate CSS class 2017-01-31 22:05:04 -08:00

bb1bcc804f Allow machine XML files to separate machine "type" from machine "class"; if present, "type" should determine the machine type, and "class" simply becomes the machine's style 2017-01-29 10:13:03 -08:00
