Description Jerome Simeon 2005-12-13 20:59:17 UTC 
fn-round-half-to-evendbl1args-1
fn-round-half-to-evendbl1args-3
  Shouldn't the result be:
   -1.7976931348623157E308
  and
    1.7976931348623157E308
  respectively?

  instead of -INF and INF

Jerome:

As per section 6.2 of the F&O specs, looks as though both results are 
correct.  I am looking at 

"For xs:float and xs:double operations, overflow behavior ·must· be conformant 
with [IEEE 754-1985]. This specification allows the following options:

Raising an error [err:FOAR0002] via an overflow trap.
Returning INF or -INF.
Returning the largest (positive or negative) non-infinite number."

I will change the test entry to account for that.  Please comment if not in 
agreement.

Thanks,
carmelo

Jerome:

oops, but this is not an overflow situation, therefore the results should be 
as you suggested.

Thanks,
Carmelo
