Decimal floating point is actually an established thing and part of the current IEEE 754 spec. I'm not too familiar with COBOL but pretty much any modern language will offer it through a library or compiler extension. Recent IBM Power processors even have hardware support.

Both you and the parent are correct. Decimal floating point is a long-established thing, but the vast majority of "Currency" or "Decimal" data types in modern languages are arbitrary or fixed precision (to some configurable precision) which uses integer math under the hood.
