The tools you provide are awesome! Helped me a lot to check my calculations! Thanks!

powMod(2,0,1) returned 1 not 0

Thanks for the tool, it is really help full for my project right now. I was wondering why you didn't implement a division operator? I try to figure out an algorithm for this one. Also how are you implementing the mod operator? Thanks.

Theres problem regarding modulo of negative values, example:a=5, b=10, c = 9, mod(sub(a,b),c) i.e. (-5 mod 9) returns 5 instead 4

I am trying to test 2048 bit RSA modulus in hex form and a large integer composite of product of all primes between 3 and 751 or GCD which should be 1, but I am getting low primes as GCD. I wonder if the tool is working correctly.

Let a = 40adbc6b19cf399c258ad4b1d27e128fa3322758b99b866042f4fedc60b200a05fbc0b798b4415b0cfea61, andb = 6c13cd835651388c48aa61bc252098b586742da7a76e9e9a6cb423.

GCD(a,b) returns 9, but GCD(b,a) returns 1.

Thanks for the great tool!!! Can you add a function to divide values? If that is too complicated then a simple shift would be great. That way I can divide numbers by 2, 4, etc which is actually exactly what I need.

muy bueno
