Overview

TextField.setString(Double.toString(Math.PI)) throws IllegalArgumentException in Series 40 2nd Edition devices.

Description

TextField.setString(Double.toString(Math.PI)) throws IllegalArgumentException in Series 40 2nd Edition devices. This appears to be because maximum amount of decimal digits is exceeded: if there are more than 8 decimal digits after the decimal point, the defined exception will be thrown. Double.toString(Math.PI) returns a String of 17 characters (15 digits).

How to reproduce

Try this:

 TextField txt;
 ..
 txt = new TextField("Value:", "", 20, TextField.DECIMAL);
 txt.setString(Double.toString(Math.PI));

Or this:

 TextField txt;
 ..
 txt = new TextField("Value:", "", 20, TextField.DECIMAL);
 textField.setString("3.141592653");

Solution

Avoid reading more than 8 digits or use String.substring(int beginIndex, int endIndex) for shortening the String or use TextField of type ANY.
