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!.

thanks!

Have you done a google search? I immediately found this library from the very active forum member Nick Gammon: http://www.gammon.com.au/Arduino/BigNumber.zip.

octaword is 128 bit, but does it work on Arduino? http://en.wikipedia.org/wiki/Integer_(computer_science)

thanks! sounds interesting but is there any explanation somewhere?
