I have found that software solutions are too slow for my application. -------------------- In main frame computers for S/370 family has quad precision and FORTRAN for that system supports the elementary functions at that precision also. For the PC, a product from Japan called UBASIC has very fast multiple precision support with a variation of BASIC program. It is very good and very fast. You can download this product which runs under DOS and it is free - not shareware. Look for UBASIC in a search engine.
