Method Detail

compare

int compare(double o1,
            double o2)

Type-Specific compare function to reduce (un)boxing

Parameters:

o1 - the first object to be compared.

o2 - the second object to be compared.

Returns:

a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.
