Correct rounding of algebraic functions

Nicolas Brisebarre, Jean-Michel Muller (2007)

RAIRO - Theoretical Informatics and Applications

We explicit the link between the computer arithmetic problem of providing correctly rounded algebraic functions and some diophantine approximation issues. This allows to get bounds on the accuracy with which intermediate calculations must be performed to correctly round these functions.

Numeric-analytical construction of Mathieu functions

Yu. A. Ryabov (1999)

Mathematica Bohemica

In this paper we present an iterative algorithm for the construction of Mathieu functions of any order N in the form of Fourier series (practically, polynomials), and also the corresponding Quick-BASIC program for realization of this algorithm with numerical values of the parameter.
