Excuse me, but why are you treating it as a decimal number rather than a binary?

It doesn't matter how you treat it or what numeral system (decimal, binary, hexadecimal,...) your code uses, as long as it is the same number.

Why is it the same number?

I added the 0b preffix to the number and got "Generator point has x or y out of range." quod erat demonstrandum.
Quick digging into the code shows that in the multiplication operator there is a modulo operation:

Code:

if self.__order: e = e % self.__order

so it doesn't matter how big number you use, the operation will be done with its modulus (which is no bigger than 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141 by the definition)

Thanks for clearing this up. I wasn't knowledgeable enough to go through the python code myself, but there had to be a modulo operation somewhere. Either that or the math is wrong.
