4. how to get a 32 bit cpu to recognize massive numbers    bytes.com

you need to write pow because the prototype for pow is double pow(double base, double exponent); that is pow is double based (in C) but you pass a 64 bit integer as the exponent. A double does not have the precision to accurately represent a 64b it integer. I double holds 16 significant digits but a 64 bit integer holds 20 ...
