calcul big numbers

Hi everybody, how can i store big numbers (more than 32 bit or 64 bit)

i have to use the pow() function but when i calculate big numbers (over 32 bit) i cannot store the result!.


Have you done a google search? I immediately found this library from the very active forum member Nick Gammon:

octaword is 128 bit, but does it work on Arduino?

thanks! sounds interesting but is there any explanation somewhere?
