i wanted to know if someone could show me how to make a funtion that will evaluate integrals for me. if not is there a way i can do factorials in qbasic? i want to make gamma and beta funtions, and the only two ways i know how to find gamma and beta for gamma and b(m,n) are to use factorials or integrals. i tried to make my own function to the factorial of a number, but it was extremely slow and could only find the factorial of any whole number>1 and i want to be able to find the factorials of numbers such as .5 also
