Issue passing numbers in store procedure

Hi All,

I have an issue storing numbers in oracle 11g. I can pass numbers with no decimals and with decimals, in my data table i see this:

1.1 (OK)

1.2000000000000002 (instead of 1.2)

1.3000000000000003 (instead of 1.3)

1.4000000000000004 (instead of 1.4)

1.5000000000000004 (instead of 1.5)

1.6000000000000005 (instead of 1.6)

1.7000000000000006 (instead of 1.7)

1.8000000000000007 (instead of 1.8)

1.9000000000000008 (instead of 1.9)

2.000000000000001 (instead of 2.0)

I am using this in cfc:

<cfstoredproc procedure="myDB.myPackage.updateTableA" datasource="mySource">

                <cfprocparam value="#arguments.myNumberValue#" cfsqltype="cf_SQL_FLOAT">

</cfstoredproc>

In oracle I have the parameter myNumberValue as number data type.

I try CF_SQL_DECIMAL and cf_SQL_NUMERIC, it doesn't pass anything.

What sql type do I use in my storedproc ?

Thanks
