Usage:
The setValue( n ) function has been over-loaded to accept multiple data
types. int, short, double, and long are all accepted and displayed
according to the attributes given in left and right accuracy.
Details:
The component will automatically redraw itself when the left and right
accuracies are mutated. If the number currently in the JMeter field has too
many digits to the left of the decimal place after the left accuracy
attribute has been modified, the number will not be displayed. However, this
is not true for the digits to the right. They will merely be rounded to the
correct decimal place.
