I'm glad that x86 has special instructions to, after adding two numbers, "clean up" the result as if those numbers had actually been BCD.

for extra credit, are these instructions actually faster than doing it in software?

it probably made sense in the 1980s when the 386 isa was defined

nothing in x86 ever seems to get removed, just more added

i tried to read a 586 architecture book once. i actually understood some of the words in it and i got the sense that x86 is legacy_support.txt

Your new processor still needs to be able to execute all your old software that you still want to use with it. If you break software compatibility it isn't really x86 any more, it's a new dialect that just happens to resemble it...

not true, x86/64 has some opcodes removed/redefined

if y'all think the ISA is saddled with a bunch of legacy garbage, the larger platform is much much worse. mrc, vga,

So tonight my first official contribution to open source got merged! It was removing an outdated lint in the Rust compiler. I feel pretty cool! Thanks to this thread for getting me inspired to actually go out and contribute. :cheers:

edit: specifically it was this post that got me to do it:

just got into an incredibly stupid discussion on facebook (!)

guy demonstrates floating point loss of precision with excel, subtracting 0.01 a hundred times from 1, result is not exactly zero. he's all insufferable nerd like "free ice cream to the first non-computer guy who can explain why in 10 words or less ", finally "ends the contest" all disappointed with his fb friends, explaining floating point, how 1/10 can't be represented exactly in base 2, etc. and some incredible poo poo on how BCD is the only way to get an exact result. what the gently caress, right? I make an effortpost on rationals and fixed point and arbitrary precision, and he uh, just does not understand what rationals are. I mean he does in a purely theoretical way but it's clear he's never used them in software like ever. seems to confuse the textual representation of 1/3 (literally infinite) with the in-memory representation (literally a 1 followed by a 3 for a total of 3 bits before rounding/overhead). he immediately moves the goalposts to a matter of orders of magnitude, who the gently caress cares though? you want approximate results but more precision than a 64 bit IEEE float, you use arbitrary precision floating point, there are plenty of libraries, nobody forces you to use the hardware-provided floats. I specifically included arbitrary precision floating point and a disclaimer about space/time complexity because you're dealing with nerds, you rules-lawyer up. also did you know that to do exact calculations with numbers like 0.1 you need a symbolic mathematics engine??? literal argument made by him, the solution to the rounding issue besides BCD (!!!)

also smug about not using windows when I told him that the windows calculator can add and subtract 0.1, 0.01, etc. just fine (of loving course it uses rationals internally, except for irrationals which are stored as decimal fixed point with IIRC 64 decimal places), so I told him, try it with bc, in fact script it with bc and see if the result isn't 100% exact every single time, must be magic or some sci-fi-level symbolic calculator poo poo and not basically 9th grade arithmetic. but no it doesn't scale and can't calculate the fisher test for a large population in useful time so it must be some toy that's never used anywhere by anyone and not say a hugely popular software package old enough to drive, vote and drink

BCD, loving seriously? he's an old so it's somewhat excusable but does he really think the world never moved on from there?

one of the early markets for microprocessors was desktop and handheld calculators. it makes sense to use bcd as the number format there since the output would have been seven segment displays for each digit and you would need to convert it to something bcd-like anyway
