4011,Strange bug may be associated with rounded_transc_opp policy,Vitor Vieira Lopes <vitor.lopes@…>,Boris Gubenko,"When I evaluate the following expression:
a = Interval(1.0, 3.0)[[BR]]
exp( a * log(0.001) )[[BR]]

I receive the result [nan ~ nan] when I select the rounded_transc_opp policy. However, if I select the rounded_transc_exact all goes well and I receive the expected result: [1E-9 ~ 0.001]

If I select the rounded_transc_opp policy and evaluate the expression:[[BR]]
exp( a * log(0.0001) )
all works well and I receive the expected result: [1E-12 ~ 0.0001]
also works well for:[[BR]]
exp( a * log(0.0011) )
but not with:[[BR]]
exp( a * log(0.00101) )

I hope that someone can look at this problem, since this is really a very strange situation.

Keep up with this excellent work and
best regards...

Vitor
