INTZ Function

Arguments

argument

is a numeric constant, variable, or expression.

The following rules apply:

• If the value of the argument is an exact integer, INTZ returns that integer.

• If the argument is positive and not an integer, INTZ returns the largest integer that is less than the argument.

• If the argument is negative and not an integer, INTZ returns the smallest integer that is greater than the argument.

Unlike the INT function, the INTZ function uses zero fuzzing. If the argument is within 1E-12 of an integer, the INT function fuzzes the result to be equal to that integer. The INTZ function does not fuzz the result. Therefore, with the INTZ function you might get unexpected results.

The following SAS statements produce these results.

var1=2.1;
a=intz(var1);
put a;

 

2

var2=-2.4;
b=intz(var2);
put b;

 

-2

var3=1+1.e-11;
c=intz(var3);
put c;

 
1

f=intz(-1.6);
put f;

 
-1
