Based on what I've learned today from reading that bug, I thin
oat in this case, you may want to be able to check that is converts into
the float as you expect and then the binary representation may make sense.

Based on what I've learned today from reading that bug, I think in Java at
least, float -> string -> float will give you back the
age-

And just need to add xsi:type to a few expected infosets that are

So Java 21 produces different floating point values in a few cases. Some of our
tests (4) are sensitive to this.
The "right way" to compare floating point numbers is like this:
If(Math.abs(A - B)
