A colleague forwarded this set of comments/questions to me and I am forwarding to the REBOL list...

Hi Doug, go to http://www.rebol.org/math/index.htmland pick up a copy of Eric Long's decimal.r. He writes: Purpose: Contains functions for the manipulation of decimal values, packaged into the REAL object. These provide full support for native binary floating-point file IO, compatible with C, FORTRAN, etc. REBOL decimal and money values may also be saved and loaded with no roundoff error. This package is necessary because the standard REBOL representation of decimal values may round off one or two significant digits, and the rounding of money values is an even greater source of error. This script contains two more objects, IEEE and EMPIRICAL, which provide several functions useful for exploring how decimal values are represented as double floating point numbers, and for testing the inexactness of the REBOL comparison functions.
