Sorry, but if you have less than a 0.000000000000(...)0001 level of doubt, it is not illogical to round it to 0. Nor is it stupid. People take .05 as enough, usually, to reject the null hypothesis. If you want it in statistical terms, that is.

In English, you can have so little doubt that it's more sensible, more logical, more intelligent, to say you have none, than to cling to that scintilla and insist it means whatever you doubt must still be possible.
