Abstract: This paper offers a general expansion formula for oscillatory integrals of the form $ \smallint _0^1{x^{ - \alpha }}f(x,\{ Nx\} )\,dx$ in which N is a large parameter, Nx denotes the fractional part of Nx, and $ \alpha $ is a fixed real number in $ 0 < \alpha < 1$. Our formula is expressed in terms of some ordinary integrals with integrands containing periodic Bernoulli functions and the generalized Riemann zeta function.
