In need to round down to the nearest whole number or simply strip everything to the right of the decimal in a numeric field. Example:
have | need |
1.2 | 1 |
0.1 | 0 |
10 | 10 |
Use the FLOOR function to round down to the next integer.
data a;
input have;
need=floor(have);
datalines;
1.2
0.1
10
123.456
34
5.1111
7.68
10.98
-3.1
-19.0
-4.8

Remember that the floor function gives you the next lower number, so 3.1 yields 3 and -3.1 yields -4. The int function will give you 3 and -3 respectively. So, choose the one that meets your specific needs.
