§23.1 states that Special units are defined with:

The BNF for the special expression is <special-unit> ::= <function-symbol>“(”<floating-point-number>“ ”<term>“)” The function symbols are defined as needed.

But there is no language explaining what <floating-point-number> means. Does it relate back to any definitions in §21 or §22? Perhaps it has something to do with one or more of the components in the quadruple s = (u, fs, fs-1, α)?

Some explanation would help.
