ACC: Attached Btrieve Table Rounds Time Values (109726)
The information in this article applies to:
- Microsoft Access 1.0
- Microsoft Access 1.1
- Microsoft Access 2.0
This article was previously published under Q109726
Moderate: Requires basic macro, coding, and interoperability skills.
SYMPTOMS
When you enter a time value such as 06:37:00 in a field in an attached
Btrieve table, the time value is changed when you exit the field. In this
example, the time value might be changed to 06:36:59.
CAUSE
This problem occurs because of differences in the way that Btrieve and
Microsoft Access store time values. Btrieve stores time values in integer
(binary) format, while Microsoft Access stores them in floating-point
(decimal) format. The conversion of decimal fractions to binary fractions
is a mathematically inexact process, and rounding errors can occur.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Access versions
1.0, 1.1, and 2.0. We are researching this problem and will post new
information here in the Microsoft Knowledge Base as it becomes available.
MORE INFORMATION
