Also change the locale in use by one of these transient changes: it purported to be checking things didn't depend on locale, but was using the same local as most of the test-cases for its test.

That also applied to values that underflowed float's range, succeeding and returning 0 as long as they were within double's range but failing if toDouble() underflowed. Now float-underflow also fails. Amended their documentation to reflect this more consistent reality. Added some tests of out-of-range values, infinities and NaNs.

They also succeeded, returning zero, on underflow of float's range, unless double underflowed, where they failed. Changed the handling of values outside float's range to match that of values outside double's range: fail, returning an infinity on overflow or zero on underflow.
