Why is it not automatically converted to long double? And I want to add to my original question: indeed I read from the docs: https://docs.python.org/3/reference/lexical_analysis.html#floating-point-literals that float has an 'exponentfloat' syntax. Why integers does not have an equivalent syntax? It's not too difficult to lexically distinguish between a integer and a float written in exponential notation, I think. -- https://mail.python.org/mailman/listinfo/python-list
