Let me give you an example, just try it on normal calculator, subtract 1 from the following and then

Digaran, stop creating mass fake accounts and spreading around. You're even using your signature ~dig OMG
This is really getting ridiculous.
In a bid to keep my research and efforts transparent and accessible, I have decided to share the GitHub repository containing my work on elliptic curve cryptography (ECC). Here's the link to the repository:
https://github.com/ecc-r/ECC-Vulnerability-Researchyour python program yields following error:
line 122, in is_point_odd
point_exponent = point_exponent(point, scalar)
^^^^^^^^^^^^^^
UnboundLocalError: cannot access local variable 'point_exponent' where it is not associated with a value
The name of the function is used as a variable in the function itself, which leads to an UnboundLocalError. To fix that bug, here's a patch...
