Could not accept negative numbers such as: "- 20.2" and will throw out an
exception, but it will accept " -20.2". We know that in many other
languages both are accepted.
Code used:
newVal = new Float((String) data).floatValue();
or:
newVal = new Float((String) data).parseFloat((String) data);
How can I solve this problem?
