Should I exit and re-enter EU with my EU passport or is it ok? u64 means an 'unsigned 64 bits' value, so, depending on the architecture where the code will run/be compiled, it must be defined differently in order to really be 64 bits long.. For instance, on a x86 machine, an unsigned long is 64 bits long, so u64 for that machine could be defined as follows:. The number in parentheses in a type declaration is display width, which is unrelated to the range of values that can be stored in a data type. The display width does not constrain the range of values that can be stored in the column, nor the number of digits that are displayed for values having a width exceeding that specified for the column. Websize_t data = 99999999; int convertdata = static_cast(data); is likely to silence the warning (though in principle a compiler can warn about anything it likes, even if there's a cast).
