Thanks for the explanation. If a model number is a number which can be
accurately representable by a computer, then I don't understand the
term machine number. On my computer I can have Long_Long_Float (18
digits). In this case is the model number precision not equal to the
machine number precision? Do you mean that machine number precision is
set say to the precision of Long_Long_Float (18 digits)? This would
make sense since any other float calculation (with fewer precision
digits) would have a model number precision less than the machine
number precision (Long_Long_Float---18 digits).
