The first comes from a Mercury program, using my work-in-progress random.m
replacement.  The second uses the canonical tt800.c .  Both have the same
seed.  I've only hacked out the second's conversion to a double, to see
why the floating-point output of both is so different.

Speaking of floats, here is an important function in my module:

:- func max_int_float = float.
max_int_float = float((integer(0xfffffff) << 4) \/ integer(0xF)).


I fear that this is going to end in tears.


Cheers,
Julian
