   ENDIF

Steps to Reproduce Behavior

Run the following code in a program file.

   *******************Begin Code****************
   CLOSE ALL
   CLEAR
   SET DECIMALS TO 10

   CREATE CURSOR test2 (f1 N(10,2))
   CREATE CURSOR test3 (f1 N(10,2))
   CREATE CURSOR test4 (f1 N(10,2))
   CREATE CURSOR test5 (f1 N(10,2))
   CREATE CURSOR test6 (f1 N(10,2))

   INSERT INTO test2 VALUES(100.01)
   INSERT INTO test2 VALUES(100.01)

   INSERT INTO test3 VALUES(100.01)
   INSERT INTO test3 VALUES(100.01)
   INSERT INTO test3 VALUES(100.01)

   INSERT INTO test4 VALUES(100.01)
   INSERT INTO test4 VALUES(100.01)
   INSERT INTO test4 VALUES(100.01)
   INSERT INTO test4 VALUES(100.01)

   INSERT INTO test5 VALUES(100.01)
   INSERT INTO test5 VALUES(100.01)
   INSERT INTO test5 VALUES(100.01)
   INSERT INTO test5 VALUES(100.01)
   INSERT INTO test5 VALUES(100.01)

   INSERT INTO test6 VALUES(100.01)
   INSERT INTO test6 VALUES(100.01)
   INSERT INTO test6 VALUES(100.01)
   INSERT INTO test6 VALUES(100.01)
   INSERT INTO test6 VALUES(100.01)
   INSERT INTO test6 VALUES(100.01)

   SELECT test2
   SUM f1 TO m.x2

   SELECT test3
   SUM f1 TO m.x3

   SELECT test4
   SUM f1 TO m.x4

   SELECT test5
   SUM f1 TO m.x5

   SELECT test6
   SUM f1 TO m.x6

   IF m.x2 <> 200.02
      ? "Mismatch 2"
   ENDIF

   IF m.x3 <> 300.03
      ? "Mismatch 3"
   ENDIF

   IF m.x4 <> 400.04
      ? "Mismatch 4"
   ENDIF

   IF m.x5 <> 500.05
      ? "Mismatch 5"
   ENDIF

   IF m.x6 <> 600.06
      ? "Mismatch 6"
   ENDIF
   *******************End Code**************************
				

Notice that there are two errors listed:

• Mismatch 3 -and-
  
  
• Mismatch 6

Another way to verify the problem is to step through the code in the Visual FoxPro Debugger. Place the following in the Watch window:

   M.X3=300.03
   M.X6=600.06
				

Both of these entries return ".F."

If you change the number of decimals to less than 10 using the SET DECIMALS TO command, the problem does not occur. Furthermore, changing the number of decimals stored in the table does not matter.
