The authors prove the asymptotic superquadratic convergence, in exact arithmetic, of \texttt{DLASQ}, a \texttt{LAPACK} routine (based on an algorithm of \textit{K. V. Fernando} and \textit{B. N. Parlett} [Numer. Math. 67, No.~2, 191--229 (1994; Zbl 0814.65036)]) which computes the singular values of a real bidiagonal matrix with high accuracy.
