I'm sure multiple variants have been implemented, Borland C++ V2.0 from 1991 (version chosen as it's on bitsavers.org) has a bcd type which IIRC uses the 80 bit 8087 packed decimal type but it's been a long time since I looked at this deeply.

I remember we had Borland Turbo Pascal 3.0 with BCD in the mid 1980s.
