Has anyone dome interval math (primitive operations on intervals) on a sparc ? It's my understanding that it's possible to write your own interval math handling procedures, given that you can control the rounding directions etc. for the math chip. I have heard of an implementation for a T800 transputer, but need something to run on a sparc (in a SUN4). The final purpose would be to implement the INTBIS interval bisection package for zero-search, in C. INTBIS is in FORTRAN, so I'd have to run it through the f2c program. Having the interval math primitives implemented by fooling around with the math chip will speed up the program A LOT. So, what I need is routines callable from CC (or GCC) compiled programs. The ideal format is probably asm{} for GCC, but that is a little far fetched.. . jensting@diku.dk is Jens Tingleff MSc EE, Research Assistent at DIKU Institute of Computer Science, Copenhagen University Snail mail: DIKU Universitetsparken 1 DK2100 KBH O
