Definition of 'significand'

Language enhancement
1

The F2023 definition of significand means that a real literal constant may have no significand, because 7.4.3.2 contains both R715 and Note 3.

R715 significand is digit-string . [ digit-string ]
                 or . digit-string

Note 3 gives 3E4 as an example of a signed real literal constant.

Am I the only person who finds that odd and thinks that something ought to be done about it?

I don’t find it odd. R714 allows a real-literal-constant without a significand

R714 real-literal-constant is significand [ exponent-letter exponent ] [ _ kind-param ]
         or digit-string exponent-letter exponent [ _ kind-param ]

You can express the real constant 2.0 in many way, including
2.0
2.
2e0
2.e0
2.0e0
.2e1

Some choices are clearer than others.
