BUG: Multiplying Numeric Datatypes May Yield Lower Precision

Last reviewed: April 10, 1997
Article ID: Q163069

The information in this article applies to:

Microsoft SQL Server, version 6.5

BUG #: 16460 (SQL6.5)

SYMPTOMS

When you multiply two highly precise numeric datatypes, you may not receive the expected precision in the result. For example, consider the following statements:

   declare @num1 numeric(28,8),@num2 numeric(28,8),@num3 numeric(28,8)
   select @num1=1.0,@num2=0.12345678
   select @num3=@num1*@num2
   select @num3

These statements return a value of 0.12345600, but they should return a value of 0.12345678.

STATUS

Microsoft has confirmed this to be a problem in Microsoft SQL Server version 6.5. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
