No.  It is just plain right.

The standard is entirely clear that assignment and casting are two cases
where a compiler is required to change the precision/representation of
an FP value exactly as called for by the type of the cast or by the type
of the expression on the left hand side of the assignment.

There is nothing in the least bit vague about this.  Those are the rules.
