SUMMARY
Having problem entering some investment transactions.  There is a slight
difference between the total amount shown in the transaction editing window and
the total amount shown in the ledger.  Does not occur very often.  Only appears
to occur with certain security.  


STEPS TO REPRODUCE
1. Create sell shares transaction
2. Set shares at 0.04348.  Set price at 197.78.
3. Total amount is shown as $8.60.  However when I press enter the ledger
indicates total amount as $8.59.

OBSERVED RESULT
Entering shares at 0.04348 and price at 197.78 total amount in editing window
is $8.60 but total amount shown in ledger is $8.59.  

EXPECTED RESULT
Amount in ledger to match amount in transaction editing window.

SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
Have fraction for shares set at 1/100000 and have tried price precision of
2,3,4,5 and 6.  Same result regardless of price precision.
