We all use decimal arithmetic for our thinking and hand calculations. It would be great if our computers did, too - for example, no rounding would be needed for formatted output. Does anyone disagree with this position? Of course, the Cobol people strongly favour retention of decimal arithmetic in the new standard. Cheers, John. _______________________________________________ ukfortran mailing list http://www.accu.org/mailman/listinfo/ukfortran I would not like to see decimal arithmetic removed totally. I do not have strong views however about the packing method. SQL has exact decimal and has had this for a long time. Microsoft Visual Basic has decimal data type C# has system.decimal. This is the same as the vb one. Microsoft Java has access to the same decimal type. The ISO JTC1/SC22/WG14 C and WG21 C++ committees are preparing Technical Reports which add the decimal types to those languages Java (through the Sun or IBM BigDecimal class) Decimal arithmetic packages are available for Eiffel and Python A good coverage is at http://www2.hursley.ibm.com/decimal/decifaq1.html And is where I located some of the above information. I think that is important that Fortran be able to address Problems in this area.
