FLOORZ(argument)

Required Argument

argument

is a numeric constant, variable, or expression.

Comparisons

Unlike the FLOOR function, the FLOORZ function uses zero fuzzing. If the argument is within 1E-12 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.

Example

The following SAS statements produce these results:

SAS Statement	Result
var1=2.1; a=floorz(var1); put a;	2
var2=-2.4; b=floorz(var2); put b;	-3
c=floorz(-1.6); put c;	-2
var6=(1.-1.e-13); d=floorz(1-1.e-13); put d;	0
e=floorz(763); put e;	763
f=floorz(-223.456); put f;	-224
