convert textfield text in to double or int

[eswar]

I need to do some mathematical operation based on textfield.

For ex:

textfield:{
id:tf1
 text:""
ontextchanged{

tf2.text=(tf1.text*50)/25
}
}
textfield:{
id:tf2
 text:""

}

Note: We enter real value (60.00) in tf1 and also we get real value(80.00) in tf2

If i use the same calculation, i get output as zero.

In that any text changed in textfield1 will automatically refeclt to the textfield2 and autocalculated value will be displayed in textfield2.

@eswar I think you should first convert it to float using parseFloat then perform calculations on it. You can find many example of JS related to it.

If i use phraseFloat , l get ouput like this
qml: NaN
qml: NaN

@eswar
Its working as per your need.

I didn't find any time zero as per you are saying...

TextField{
    id:tf1
    text:""
    width: 50
    onTextChanged: {
        tf2.text=(tf1.text*50)/25
        console.log(tf2.text);
    }
    }
    TextField{
    id:tf2
    text:""
    x:tf1.width + 50
    }

In that above method , based on the textfield1 the data in the textfield 2 is changed. In that textfield 2 , i set validator. The value lies in between 0 to 1000 will be apper in tf2. I entered higher value, the tf2 value will appear any values . The tf2 validator will not validate tf2 data. In tf2 the value only 0 to 1000 will be appear , if i enter any value in tf1. How can i achieve that?
