It wasn't required at my school a decade or two later. Floating point representations were touched on somewhat in the intro to computer architecture class where we wrote assembly for a MIPS simulator. I got an extra dose because I switched my major to Math, where there was an entire course on Numerical Methods (though it wasn't required by either the Math or CS depts). I'm a little amazed in retrospect that the Math department was where one had to go to get a class in the mechanical details of computing when as a subject it's usually considered (and often in practice is) notably up the ladder of abstraction. And this was a weird outlier as the single most practical upper division class offered by the Math department at the time...
