Question

I am new to Qt Creator. I would like to convert a QString value into a long number. How would I do this?

long s;
QString x = "6458621237";

EDIT

As a result I’ll have long s = 6458621237;

Answer 1

Use the toLong function.

For example,

 QString str = "FF";
 bool ok;

 long hex = str.toLong(&ok, 16);     // hex == 255, ok == true
 long dec = str.toLong(&ok, 10);     // dec == 0, ok == false
