Returns a vector containing the results of comparing each set of corresponding elements of the given vectors for equality.
Elemental function
If ARG1 is an INTEGER(1) vector or UNSIGNED(1) vector, then the result is an UNSIGNED(1) vector. If ARG1 is an INTEGER(2) vector or UNSIGNED(2) vector, then the result is an UNSIGNED(2) vector. Otherwise, the result is an UNSIGNED(4) vector.
For each element of the result, the value of each bit is 1 if the corresponding elements of ARG1 and ARG2 are equal. Otherwise, the value of each bit is 0.
