Sorry, but no idea what this means. Have googled around uint64_t for a while but the articles are too technical for me to be able to understand. The unit64_t is a 64-bit integer data type defined by the C and C++

In general, a number is represented in a computer as either an integer (or a
whole number), or as a floating point (eg. decimal) number. Floating point
is essentially what some non-programmers might know as scientific notation.
A floating point number has a mantissa, an exponent, and a sign (+ or -).
Both integers and floating point have hardware (called registers) where the
numbers can be operated on. when we talk 32-bit and 64-bit we generally
mean addresses (or places in memory where things can be stored), or
integers. The maximum unsigned decimal value that can be stored in a 32-bit
register is 4294967295, and a maximum unsigned decimal value that can be
stored is 18446744073709551615. What this means in very general terms of
memory is that a program can only address 4GB of memory in a 32-bit system.
remember, this 4GB limit also applies to disk files and other things.
