Hello

I was solving this question where a very large number 16^123 is involved. As I have a habit of ‘seeing’ everything as programming problems, I realized that if I can just calculate 16^123 which is 22142024630120207368183773162315510695991025691578204136484229989042903038958701481563926559866088068

690875167586818560952715154383806383816600300027904 and then take its modulus by 257, I get the answer. But the data type required to store such a huge number is probably long double and any data type involving floating points cannot be used in modulo arithmetic.

So, I was wondering if there was a way that such huge numbers can be converted to integers( or numbers without decimals) and still modulo arithmetic be used on it?

Thanks
