Abstract

Numerical integration is an important operation for scientific computations.Although the different quadrature methods have been well studied from amathematical point of view, the analysis of the actual error when performingthe quadrature on a computer is often neglected. This step is however requiredfor certified arithmetics.
We study the Newton-Cotes quadrature scheme in the context ofmultiple-precision arithmetic and give enough details on thealgorithms and the error bounds to enable software developers to write aNewton-Cotes quadrature with bounded error.
