problems dividing two columns

powder — Fri, 16 Mar 2012 16:18:59 GMT

Using SAS EG 4.3 when I go to divide the two columns the results returned is always zero. I've tried different formats, etc. However the same two columns can be added, subtracted, multiplied no issues. See code and output below for details. Thanks in advance.

Code:

t1.Region,

/* TC_Tasks */

(SUM(t1.MeasureCount)) FORMAT=11. LABEL="TC_Tasks" AS TC_Tasks,

/* TC_Tasks_Met */

(SUM(CASE

WHEN t1.HourDefferedCount <= 4 And MeasureCount = 1 THEN 1

ELSE 0

END)) FORMAT=11. LABEL="TC_Tasks_Met" AS TC_Tasks_Met,

/* TC_Tasks_Met1 */

((SUM(CASE

WHEN t1.HourDefferedCount <= 4 And MeasureCount = 1 THEN 1

ELSE 0

END)) / (SUM(t1.MeasureCount))) FORMAT=BEST10.9 LABEL="TC_Tasks_Met1" AS TC_Tasks_Met1,

TC_Tasks	TC_Tasks_Met	TC_Tasks_Met1
594	492	0
1805	1275	0
1791	1242	0
568	446	0
2462	1656	0

Hi,

I made up a dataset and ran your code. I don't have the problem you described and I ran the code in EG4.3

data test;

input MeasureCount HourDefferedCount;

cards;

1 3

2 4

3 1

0 5

1 6

0 1

1 2

1 3

0 4

1 5

0 6

1 7

;

proc sql;

select /* TC_Tasks */

(SUM(t1.MeasureCount)) FORMAT=11. LABEL="TC_Tasks" AS TC_Tasks,

/* TC_Tasks_Met */

(SUM(CASE

WHEN t1.HourDefferedCount <= 4 And MeasureCount = 1 THEN 1

ELSE 0

END)) FORMAT=11. LABEL="TC_Tasks_Met" AS TC_Tasks_Met,

/* TC_Tasks_Met1 */

((SUM(CASE

WHEN t1.HourDefferedCount <= 4 And MeasureCount = 1 THEN 1

ELSE 0

END)) / (SUM(t1.MeasureCount))) FORMAT=BEST10.9 LABEL="TC_Tasks_Met1" AS TC_Tasks_Met1

from test as t1;

quit;

The SAS System

TC_Tasks	TC_Tasks_Met	TC_Tasks_Met1
11	3	0.27272727

and your code is the same as

proc sql;

select /* TC_Tasks */

(SUM(t1.MeasureCount)) FORMAT=11. LABEL="TC_Tasks" AS TC_Tasks,

/* TC_Tasks_Met */

(SUM(CASE

WHEN t1.HourDefferedCount <= 4 And MeasureCount = 1 THEN 1

ELSE 0

END)) FORMAT=11. LABEL="TC_Tasks_Met" AS TC_Tasks_Met,

/* TC_Tasks_Met1 */

calculated TC_Tasks_Met

/ calculated TC_Tasks FORMAT=BEST10.9 LABEL="TC_Tasks_Met1" AS TC_Tasks_Met1

from test as t1;

quit;
