compareTo in interface Comparable<PrmNumber>

Parameters:

obj - the Object to be compared.

Returns:

the value 0 if the argument is a PrmNumber numerically equal to this PrmNumber; a value less than 0 if the argument is a PrmNumber numerically greater than this PrmNumber, or if the argument is not a PrmNumber; and a value greater than 0 if the argument is a PrmNumber numerically less than this PrmNumber.
