Incorrect Calculator Results Using Percent Key

 Last reviewed: August 22, 1995
Article ID: Q132984
The information in this article applies to:
  • Microsoft Windows 95

SYMPTOMS

When you use the Calculator tool, you may receive an incorrect result if you multiply, divide, add, or subtract after using the percent (%) key.

CAUSE

When you use the percent key followed by an operator, Calculator performs a multiplication operation regardless of which operator you use.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Windows versions 3.1 and 3.11, Microsoft Windows NT versions 3.1 and 3.5, and Microsoft Windows 95. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

MORE INFORMATION

The calculation 

   500 * 5% = 25 + = 525
demonstrates the Calculator error. If you perform this calculation with Calculator, you receive a result of 12,500 instead of 525

NOTE: Application Note WW1138 contains an updated Calc.exe file to correct a problem with reliably subtracting two numbers with decimal values. Application Note WW1138 does not solve the problem described in this article.
