Function average_pair

cpp_core/src/scf.cpp:655–657

Formula: avg = 0.5 * (a + b) Example input: a=2.0, b=6.0 Example output: avg=4.0

// Example input: a=2.0, b=6.0
// Example output: avg=4.0
double average_pair(double a, double b) {
    return half_value(a + b);
}

// Formula: v_sum = a + b + c
// Example input: a=1.0, b=2.0, c=3.0
