I am not able to find any previous discussion about this argument not in discourse nor in FAQ, so I don't know if anyone already solved this kind of problem.

I'm using Processing 0135 on Mac OSX 10.5.2 in italian language, with Interfascia 003 user interface library.

I wrote this code to range check the input on a text field:

float RangeCheckFloat(String Data, float Min, float Max)
{
   float FloatNum = 0;
   if (Data.length() != 0)
   {
     FloatNum = Float.parseFloat(Data);
     if (FloatNum < Min) FloatNum = Min;
     if (FloatNum > Max) FloatNum = Max;
     TxFlag = true;
   }
   return FloatNum;
}

the function is called in this way:

   BtnSendSpeed.update();
   if (BtnSendSpeed.released)
   {
     DesSpeed = RangeCheckFloat(InputSpeed.getValue(), -500, 500);
     InputSpeed.setValue(nf(DesSpeed,5,2));
   }
   BtnSendSpeed.display();

So, nf() translates the float value with "," (comma) decimal separation. Reading again the input field with Float.parseFloat(Data), it returns an error because it looks for a "." decimal separator.

Is there any way (other then permanently change OS language) to make both the functions working in the same way?

A working simulation example of what I'm trying to do, can be found here:

Thank you in advance to anyone who will help me.
