Invalid interval component due to precision?

[b1rd1e]

Hi,

Could you tell why the following error is being thrown? Are the operators used not able to handle this much precision?

Error1:
Traceback (most recent call last):
File "c.py", line 78, in
input_prev[index] = interval(lower,upper)
File "path/python2.7/site-packages/interval/init.py", line 101, in new

interval.ComponentError: Invalid interval component: interval([0.020530565167243362, 0.020530565167243373])

Similarly,
File "/path/python2.7/site-packages/interval/init.py", line 100, in process
raise cls.ComponentError("Invalid interval component: " + repr(x))
interval.ComponentError: Invalid interval component: interval([0.004029219530949634, 0.004029219530949636])

I cannot reproduce it. Both intervals seem to be perfectly fine:

>>> from interval import interval
>>> interval([0.020530565167243362, 0.020530565167243373])
>>> interval([0.004029219530949634, 0.004029219530949636])

I need more context to be able to diagnose what is wrong.
