C# is where it can come from:

http://www.yoda.arachsys.com/csharp/decimal.html

In general, however, it is not a fault of C# or the poster; it
is easy to make the mistake with most other numeric types derived
from binary representations.

It is a trap for a user to provide floating point inexact types
defined by restriction of an exact rational type.
