SYMPTOMS
The INT function in QuickBasic version 1.00 for the Macintosh rounds large negative numbers incorrectly in compiled programs. This problem does not occur when programs are run inside the QuickBasic 1.00 interpreter environment.

Microsoft has confirmed this to be a bug in Microsoft QuickBasic version 1.00 for the Macintosh. This problem is corrected by Microsoft QuickBasic versions 1.00a (and 1.00b).



MORE INFORMATION
The following sample code demonstrates the incorrect results in a compiled program:

FOR i% = 1 TO 6 A# = (((10^i%) * -1234#) + .5) PRINT A#, INT(A#) NEXT i%
