I have the below example SAS code, which output ht2 using input with informat 3. My understanding of ht2 =INPUT(ht,3.) is that ht will be output if has 3 digits (including decimal). But instead in the below code all of ht2 are missing.

data left;
    input  name $ ht ;
    datalines;

dick  20.55 

sam  2.5
roger  2 
peter 200 
;
run;

data left2;

set left;
ht2= INPUT(ht,3.);
run;

SAS’ Output of left2
| name | ht | ht2 |
| ——– | ————– | ——– | ————– |
| dick | 20.55| . |
| sam | 2.5 | . |
| roger | 2 | . |
| peter | 200 | . |

Expected Output of left2
| name | ht | ht2 |
| ——– | ————– | ——– | ————– |
| dick | 20.55| . |
| sam | 2.5 | 2.5 |
| roger | 2 | 2 |
| peter | 200 | 200 |
