The range and precision of Float are implementation-defined and change
between e.g. 32-bit, 64-bit platforms and Intel platforms where there
is a 80-bit floating-point type and PowerPC that has a 128-bit
floating-point type. Therefore you should not use Float. Define your
own floating-point type such that its representation matches that of
Visual Basic.
