Fix for bug 963

Browse Source 
When using FloatingPointValidator and calculating the min / max
range as floats or doubles, the validated control value has been
rounded to 'n' decimal places, but the min / max range have not
been rounded. It is therefore a matter of chance whether the
rounded control value, when at the extreme limit of the range,
is within the higher precision range or not.
