I created a query and tested in SQL Server Query Analyzer.  The query returns a number that is stored as 1.0947 as data type money to 8 digits. But when I run this query from PHP 

$dbTradeRow=mssql_fetch_object($trades_result) 

to retrieve the data and check that column, it returns only 1.09 and i loose the last two digits. Can somebody please help me out?

Replaced the php.exe & php4ts.dll files and verified the new version with phpinfo().  But problem still persisted.  Is this because php utilizes the local computer's currency settings?  Which I assume default for Windows is two decimal places?  That wouldn't be cool to have to change that default just for this instance... ideas?

try it?

Did changing the currency settings affect this or not?

I did not try modifying the locale format.  My solution was just modifying the data type in SQL Server so it was a decimal instead of money.  All is well.

updating php.exe and php4ts.dll is not enough. all the mssql functions are located in php_mssql.dll.

MSSQL server will return 2 digits after the decimal point for money and small money solumns.

You can use the convert() function to increase this to 4 digits.
