My system is 32-bit.
64-bit applications will not run on my system.
So in the above code, why should we use qint64?

The "Q"
Re: A question about uint 8 and uint 16 and uint 32 and uint 64
quint64 is just a datatype (mapping to unsigned long long or something similar), it has nothing to do with the width of the address or data bus which is what makes a system "32 bit" or "64 bit". The processor can handle 32 bit as well as 64 bit datatypes and maybe even 128 bit types as well, it is just a matter of efficiency of processing such data.Originally Posted by rezas1000

Exactly!
A "double" for example is always 64 bit, it is specified that way https://en.wikipedia.org/wiki/Double_precision
