I need help with this rounding:

var v3 = (this.getField("valor_for").value-10)/2;

event.value = Math.floor(v3);

I need the value of the operation always be rounded down

thanks

Correct answer Karl Heinz Kremer

A good way to debug these things (besides actually running in the JavaScript debugger and stepping through your code one line at a time) is to add debug output to your script. Add these two lines just after you calculate v3:

console.println("v3 = " + v3);
console.println("Math.floor(v3) = " + Math.floor(v3));

Now you can see what your script does. It works correctly for me.

If you are not getting the correct results, and if the value of the "valor_for" field is calculated as well, you need to check your calculation order (which is what I think Bernd wanted to say): If the 2nd field gets calculated before the results of the first field are available, then you are working with the previous value, which could explain the behavior you are seeing.
