Hi,
I am using Intel Visual Fortran Compiler for windows.
It only provides the single-, double-, and quadruple-precision numbers.
But I now need to perform very accurate calculations.
Is there any way to obtain, within the Intel Visual Fortran for windows,
the octuple- and even arbitrary-precision floating-point formats?
Thank you very much for your help!

Thanks, Les, for the link to the Fortran wiki which I was not aware of until now.

If you are willing to work with a library which only has a C language interface, investigate MPFR. See http://www.mpfr.org/ It's a high quality arbitrary-precision math library which produces correctly rounded results. It is used by many of the compilers in the GNU compiler collection during compilation; it is not required at run-time.
There was a discussion in 2011 on comp.lang.fortran about using MPFR from Fortran. Seach the newsgroup for the thread titled "arbitrary precision".
I'm not aware that anyone has implemented a Fortran interface to MPFR.
