Text output should use outward rounding about pyibex

[ThomasLeMezo]

The matter is that python doesn't show all the digits. If you print the lower and upper bound of your interval, you should have correct values

>>> c = pyIbex.exp(Interval(1))
>>> Interval.lb(c)
2.7182818284590433
>>> Interval.ub(c)
2.718281828459048

Yes, as you can see, the interval boundaries cover a different interval than is written in the console. In these examples the intervals are disjoint, but should be subsets. Another example:

>>> 2 * pyIbex.asin(Interval(0, 1))
[0, 3.14159]

The interval covers π internally, which is good, but the output suggests that π is not contained in the interval.

Thanks for reporting the issue.
I will work on that.

The method str and repr can be overloaded to show more digits.
For instance with

def myPrint(itv):
    return "[%3.16f, %3.16f]" % (itv.lb(), itv.ub())
Interval.__str__ = myPrint

print(Interval(2.3442, 21.3212) )
>>> [2.3441999999999998, 21.3212000000000010]
