This error is most damaging if the quoting software is using a cache memory somewhere. The wrong decimal digit may stay in the cache and cause a long series of bad quotes. For Reuters page data, this was a dominant error type around 1988! Nowadays, this error type seems to be rare.
The above patent application deals with something different. It's a method for filtering out the so called "bad ticks". One of the errors that the method is claiming to correct is the "decimal error" caused by a higher order decimal symbol not being flushed from the cache in time.
Inspirational reading, thanks. Should I file a patent application for some of my various observations, too? )
Have a great day,
