qstring k="100.1",how to convert to int = 100 ?

when i invoke toInt(), it return 0.
now i first use atoi(), and then QString::number();
but, it seems too much procedure???
how can i do that only using QString's method ?
thanks.

Try

Code:

---

QString::toDouble();

---

and then take the integer part!
:D

Alternatively, you can strip the decimals away from the string:

Code:

---

QString str("100.1");
int number = str.left(str.indexOf('.')).toInt(); // == 100

---

Works even if there isn't a decimal part, because str.left(-1) returns the whole string.

for me this should be enough:

Code:

---

QString str("100.1");
int x = str.toDouble();

---

i appreciate all the replyies ;)
