A computer represents information in groups of 64 bits. How many different integers can be represented in BCD code?
문제
This from my Interview-MCQ module:
A computer represents information in groups of 64 bits. How many different integers can be represented in BCD code?
The given answer is 1016, however no explanation is provided, I was just wondering if somebody could help me understand the answer.

BCD is binary coded decimal. In BCD, every 4 bits is used to represent a single digit from 0 to 9. So if you have 64 bits, that gives you 64/4 = 16 decimal digits, which means you can have 10^16 different integers.
