python - Why is rounding done like this? -


why python rounding this?

>>> 1.12345678901234567890 1.1234567890123457 >>> 0.0001100110011001100110011001100110011001100110011 0.00011001100110011001

in particular example, python chooses use representation has limited number of digits (depends on python version). internally, different float values may share same (rounded) representation.
