Max and Min Values for qint64

[gmat4321]

Are there constants that define the maximum and minimum values for a qint64?

Your system might define LLONG_MIN and LLONG_MAX in climits (or limits.h). You could define them yourself:

const qint64 llong_max = Q_INT64_C(9223372036854775807);
const qint64 llong_min = Q_INT64_C(-(llong_max) - 1);    
// const qint64 llong_min = Q_INT64_C(-9223372036854775808);   Generates a warning in my compiler

const qint64 llong_max = Q_INT64_C(9223372036854775807);
const qint64 llong_min = Q_INT64_C(-(llong_max) - 1);    
// const qint64 llong_min = Q_INT64_C(-9223372036854775808);   Generates a warning in my compiler

Hi, since qint64 is just a typedef you should be able to use

std::numeric_limits < qint64 >::max() and ...min()

std::numeric_limits < qint64 >::max() and ...min()

To copy to clipboard, switch view to plain text mode 

to get the maximum/minimum.

Indeed you can. I should have coffee before I visit these forums in the morning
