Is there some way of obtaining more numerical precision other than what is available

[R. T. (Fortran Man)]

Is there some way of obtaining more numerical precision other than what is available through LF90?

[Lahey Support]

There are several multiple-precision (MP) libraries available for working with numbers that require precision greater than that provided by Fortran's double precision floating point. These libraries are public domain and are available via Brent's MP package http://www.netlib.org/bmp/index.html, Bailey's MP package http://www.netlib.org/mpfun/index.html, or Smith's FM package http://cse.eng.lmu.edu/~dsmith/FMLIB.html.
