output only 2 decimal places

I have some code in which a user enters a number and depending on the scope of the number different functions are called when they click the solve button. This is done using the function below, I have also put the code at the bottom relating to the solve button.

How can I get the output to show only two decimal places?????

function inputtest(form) {
var val = "-" + tonum(form.inField.value);
var result;

if (val <=-6 && val >=-20) {
result = solve_quad(val);
}
else {
if (val<=-20 && val >=-50) {
result = solve_quad2(val);
}
else {
if (val<-50) {
result = solve_quad3(val);
}
}
}

form.outField.value = result;
}

The code I have for the output is as follows

<input type="button" name="btn12" value="Solve" onClick="inputtest(this.form)" />

In more modern browsers you can use toFixed method
Code:
```var i = 111.123456;
alert(i.toFixed(2));```

Thanks Joe

I also found this bit of code and it works a treat

result=(Math.round(result*100)/100);
