And CPUs still do it to this day. Nasty, nasty maths involved in figuring out an optimal combination between lookup table size and refinement calculations because that output can’t be approximate, it has to work how IEEE floats are supposed to work. Pure numerology.
Anyone who has ever had to maintain old code will tell you that this more civilized age is right now and that the past was a dark and terrible time.
Seriously, there were no standards, there was barely any documentation even in large organizations and people did things all the time that would get you fired on the spot today. Sure, you had the occasional wunderkind performing amazing feats on hardware that had no business of running these things, but this was not the norm.
Tons of software did this for the longest time. Lookup tables have been a staple of home computing for as long as home computers have existed.

I really like reading people talk about how better programmers in a more civilized age could do things.
