The value 1.5 should be an f_float value as well:

 This seems very strange to me... Pascal isn't supposed to have such
strong typing, is it?  I don't remember ever having to manually coerce
anything.  Or is f_float sufficiently different from a normal float?

Why didn't I do this?
I did think about it, but what about more complicated expression.
x := 1.5 * 1.5;
Is that multiply an IEEE S_float multiply or VAX F_float multiply? Logically, it would have been an IEEE S_float multiply and then converted to VAX F_float.  I didn't think it was a problem that needed to be solved.
Pascal was the first to let you mix both kinds of floats in the same module (or so I think).  The %F_FLOAT was designed to solve the LIB$WAIT issue when IEEE floating was enabled (yes, I know about the extra argument to LIB$WAIT).
