May10 comment Modulo in e-voting paper is wrong? Excellent answer. I am choosing it as best answer. Thank you! May10 comment Modulo in e-voting paper is wrong? @TMM I can not understand why 17^1/121 is 15. Isn't it the same with 17^17 which makes 240? May10 comment Modulo in e-voting paper is wrong? @TMM thank you. I'll find what I am doing wrong now May10 comment Modulo in e-voting paper is wrong? I get d= 17 and e = 240... May10 comment Computing $a^r \bmod n$ for a real number $r < 1$ @TMM Thanks a lot. I haven't found however any solution at my specific problem, if you want to take a look math.stackexchange.com/questions/387827/… . I do not have enough reputation yet to upvote your answer. If I get some, I'll upvote it for sure. :) May10 comment Computing $a^r \bmod n$ for a real number $r < 1$ Thanks a lot.

If I have the number 100 and the number 257 is my modulo number, then how I can choose the powers, in order to get number 100 bavk, when I apply these two powers? May10 comment Computing $a^r \bmod n$ for a real number $r < 1$ @TMM Thank you. However, when I try to do the equation above at the website ptrow.com/perl/calculator.pl it gives me 141 as final result instead of 100. The same does the program I have written as well (141 too!). I do not know what I am doing wrong... May10 comment Computing $a^r \bmod n$ for a real number $r < 1$ @TMM Thank you very much. I was (and am) a little confused. If I have (100 ^ 121) mod 257 then ((100 ^ 121) mod 257) ^ (1/121) mod 257 than the result of the second equation is equal to 100?

May10 comment Computing $a^r \bmod n$ for a real number $r < 1$ @TMM Thank you. I will try it now, and I will tell you if I can do this works.
