Handle correct behavior when executing DIV instruction. Flag underflow if result with unbounded exponent would lie between +/-b^(emin). Even if rounded result is exactly [+/-]01.000000. Use ex4_denorm_potnt_norm, a flag that is set when a denormal result rounds to a normal result. Signed-off-by: Greg Davill <[email protected]>
