No, since you didn't bother to tell us anything. The code does exactly what you told it to do, so it's working.

>> (L (APR/1200.0) * pow(brac1,N) ) / (pow(brac2,N) - 1.0);

I think you meant, :

(L * (APR/1200.0) *  pow(brac1,N) )  /  ( pow(brac2,N) - 1.0 );

You know its easier if you do something like this :

// (L  * (APR/1200.0) *  pow(brac1,N) ) /  (pow(brac2,N) - 1.0);
double term1 = L * APR/1200.0;
double term2 = pos(brac1,N); 
double term3 = pow(brac2,N) - 1.0;
double payment = term1 * term2 / term3;

Note that term1,2,3 are bad names. Give them something more meaningful. Dividing the equation into pieces and conquering it is a common strategy. That way you will see the error better.
