Functions and CALL Routines 
Returns the largest integer that is less than or equal to the
argument, fuzzed to avoid unexpected floatingpoint results.

argument

specifies a numeric constant, variable,
or expression.
If the argument is within 1E12 of an
integer, the function returns that integer.
Unlike the FLOORZ function, the FLOOR
function fuzzes the result. If the argument is within 1E12 of an integer,
the FLOOR function fuzzes the result to be equal to that integer. The FLOORZ
function does not fuzz the result. Therefore, with the FLOORZ function you
might get unexpected results.
The following SAS statements produce these results.
