How do I avoid scientific notation for large numbers?

Question

I am doing 2^1000 and I am getting this:

1.07151e+301

Is there any way to actually turn this into a proper number without the e+301, or at least can anyone s

Answer 1

Include the header limits.h and cmath.h

cout.precision(0);
cout<< fixed<< pow(2,31);               //OR ANY NUMBER HERE

Use cout.precision to set the precision.
