Syntax

FLOOR (argument)


Arguments

argument

specifies a numeric constant, variable, or expression.


Details

If the argument is within 1E-12 of an integer, the function returns that integer.


Comparisons

Unlike the FLOORZ function, the FLOOR function fuzzes the result. 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.


Examples

The following SAS statements produce these results.

SAS Statements Results
var1=2.1;
a=floor(var1);
put a;
 

2
var2=-2.4;
b=floor(var2);
put b;
 

-3
c=floor(-1.6);
put c;
 
-2
d=floor(1.-1.e-13);
put d;
 
1
e=floor(763);
put e;
 
763
f=floor(-223.456);
put f;
 
-224
