General moments of roundoff error

Abstract Li and Nadarajah [Signal Processing 127 (2016) 185–190] derived expressions for mean and variance of roundoff error for any continuous random variable. Here, we derive expressions for general moments of the roundoff error, allowing one to study other aspects of roundoff error than just mean and variance. The expressions are specialized for 10 commonly used distributions in signal processing. Numerical studies checking the correctness of the derived expressions are given.
