Formatting Text File Output

Post by carlhelquist » Wed Dec 03, 2008 8:35 pm

I am trying to write decimal values to a text file formatted so that there is a specific number of precision after the decimal point. I seem to be overlooking something very basic about how argDec() and Strings work and I am stuck.

Here is what I have tried so far:

function main() {

var pi=Math.PI;
var piString = new String;
var formatted = new String;

var fileout=new File('c:/pi.txt');;

fileout.writeLine('pi = '+pi);

piString = pi.toString();
formatted = piString.argDec(piString,3,'e',2);
fileout.writeLine('piString = '+piString);
fileout.writeLine('formatted = '+formatted);



This is what pi.txt looks like:

pi = 3.141592653589793
piString = 3.141592653589793
formatted = 3.141592653589793

And the message that pops up in the scripting output:

QString::arg: Argument missing: 3.141592653589793, 3.14159

Can anyone help?

String.argDec() This function is not available in Qt Script. Use replace() or concat() instead.
