The following code example using the FIX function produces different
results inside the QB.EXE environment and as an executable EXE file.
Compiling the program with the BC /O compiling option and the debug
(/d) option does not affect the results.

Microsoft has confirmed this to be a problem in QuickBASIC Versions
4.00, 4.00b, and 4.50, and in the Microsoft BASIC Compiler Versions
6.00 and 6.00b for MS-DOS and OS/2 (buglist6.00, buglist6.00b). This
problem has been corrected in the Microsoft BASIC Compiler Version
7.00 (fixlist7.00).

The following code example demonstrates the problem:

   N! = -21
   PRINT FIX(N! * 10 ^ 2)

The following is a workaround for the problem:

   N! = -21
   PRINT FIX(N!) * 10 ^ 2
