Yes I agree with you it is returning 0. If i replace 0 with any other variable then it results that variable. But in actual code alongwith other functions it returns the float A. If I replace the 0 with any variable it results with that variable. My doubt was as to what exactly that return will do there or return in such cases used for. Can anybody explain me how the returns works and where it has to be used.
Thankyou.
