That depends of SET("Decimals"), You must change Your current SET DECIMALS TO so the TRANSFORM can hadle it corectly i.e.:

old_decimals = SET("DECIMALS")
SET DECIMALS TO 5 && or any other number bigger then 2

REPORT FORM... && Here You have TRANSFORM(123.456,'999.999') 

SET DECIMALS TO &old_decimals && Restore Your default decimals number

>Got a small problem with TRANSFORM. When I use the format, it is rounding up the last digit. for example, TRANSFORM(123.456) returns 123.456 and TRANSFORM(123.456,'999.999') returns 123.460
>Any work around for this?
