64 bit unsigned integer data type (equivalent of C99 'uint64_t'). A 64 bit unsigned integer can range from 0 to 0xFFFFFFFFFFFFFFFF (18,446,744,073,709,551,615).
Usage
Used in the declaration section of code, which is before any statements.
Example
uint64 aUint64; // A stand alone declaration of a uint64. uint64 a, b; // Declaring two uint64s at the same time. uint64 c = 64000, d = 10; // Declaring two uint64s, and initializing them both at the same time.
Remarks
Unlike other languages, the uint64 data type is actually a class.
uint64 is equivalent to an unsigned long long in C.
