Whereas most scientific computing is done with conventional 64-bit computer arithmetic, a growing body of computations, particularly in the area of mathematical physics, requires more. "Double-double" (approx. 31 digits), "quad-double" (approx. 62 digits) and arbitrary precision arithmetic are all part of the new landscape. This talk will summarize some of these physics applications, and focus in particular on some intriguing applications where very high precision arithmetic (hundreds or thousands of digits) has been used to discover new evaluations for integrals that arise in mathematical physics settings.
