Variable-precision arithmetic considered perilous - a detective story
Electronic transactions on numerical analysis, Tome 28 (2008)
In 2002, I was interested in computations to very high precision, having been challenged by Nick Trefethen to compute a number he called $\tau$ up to 10000 digits. This number is the sum of ten other numbers, each of which was defined by a difficult computational problem. The story is told in [F. Bornemann, D. Laurie et al., The SIAM 100-Digit Challenge: A Study in High-Accuracy Numerical Computing, SIAM, Philadelphia (2004)].
