I have column with field type DOUBLE PRECISION and needs to convert it to DECIMAL (15,4). In a test with a field value of 23.999999, I change it to DECIMAL (15,4) and got want I need in my Delphi (DBX) application of 24.0000. Then I change it back to DOUBLE PRECISION and notice that the value is again 23.999999. I presume firebird (2.51 32bit) does not change the stored value when changing the type. My question is now, if I change the type to DECIMAL (15,4) will Firebird use 23.999999 or 24.0 in calculations in stored procedures, etc?
Any help / explanation will be much appreciate. Regards Cornie van Schoor
