Examples of net.sf.saxon.value.NumericValue.compareTo()

net.sf.saxon.value.NumericValue.compareTo()
Compare the value to another numeric value @exception ClassCastException if the other value is not a NumericValue(the parameter is declared as Object to satisfy the Comparable interface) @param other The other numeric value @return -1 if this one is the lower, 0 if they are numerically equal,+1 if this one is the higher, or if either value is NaN. Where NaN values are involved, they should be handled by the caller before invoking this method.
