Wow, pretty sure I've never seen this feature in any other language...
@leeb The IBM 1401 computer had optional support for math with pounds/shillings/pence in hardware, back when there were 12 pence in a shilling and 20 shillings in a pound. Of course there were two incompatible standards, so the computer had a knob on the front panel to select the standard.
@kenshirriff @leeb computers should still have physical dials for settings. Give me a big old Dark Mode switch I can flick.
