Not a machine, but a number of programming languages provide this option.

For example, the Rexx language has a 'NUMERIC FUZZ n' setting, which reduces
the working precision by n digits for compare operations.  (This option was
a refinement on an idea from some earlier languages -- I forget which.)

Details are in ANSI Standard X3.274-1996 or any good Rexx book.
