	That removes all modern hardware units using IEEE floating point
standard, and pretty much all languages since (including) the first version
of FORTRAN.

	Floating point numbers are x-significant digits (commonly x:7 for
single precision and x:15 for double precision) with an exponent.

	Ada supports float and fixed point, but fixed point most easily
visualized as an integer with a scaling factor.

	Use COBOL then... One used to have to go out of their way to get a
"floating point" data type in COBOL... The common numeric type is packed
BCD.

	Even M$ "money" datatype uses four decimal places even if only two are
displayed to the user -- it allows for accumulation of fractions of a cent
over time.
