I’m really surprised with that, that someone with such broad interests never heard of BCD. I mean, there’s is always something new to learn all the time, don’t get me wrong, nothing to criticize, just plain surprised. Wonder if that is just something older people came across?

Old PL/I programmer here. I’m still trying to forget BCD’s from the 80’s!

I learned about BCD when I was learning x86 assembly and have never came across them later. They are gone in x64.

I did learn binary-coded decimals in college 5 years ago.
