Autumn 1992, in an undergraduate industrial placement, a module for approximating special functions (Zeta function, Bessel functions etc) in the REDUCE computer algebra system: https://sourceforge.net/p/reduce-algebra/code/HEAD/tree/trunk/packages/specfn/specfn.red https://sourceforge.net/p/reduce-algebra/code/HEAD/tree/trun... I kept a copy of Abramowitz and Stegun open on the desk for months... I don't think REDUCE is all that widely used nowadays, but it does still work, very well in some respects. It was closed-source at the time and was open sourced relatively recently. I'll echo the sentiment that most of the commercial stuff I've worked on has either died or never launched at all.
