Provably Fair PrimeDice

[tchoob]

Hello,

i'm actually studying c# and i have to make a provably fair for my dice game,
I trying to reproduce an algorithm similar to that of primedice but i didn't understand why they are doing a " 697969%(10000)/100 " , can someone explain it to me please ?

Thats simple.

697969 is the random number generated.

Modulo 10000 is used to get a number between 0 and 10000, which will then be divided by 100 to get a number between 0 and 100 with 2 digits behind the comma.
This is done because primedice wants to generate numbers in this format.
