What VMS float types are SQL_C_REAL, SQL_C_DOUBLE, and SQL_C_FLOAT?

We build the Easysoft ODBC-ODBC Bridge for OpenVMS with the DECC qualifier /FLOAT=G_FLOAT.

An SQL_C_REAL should be a F_FLOAT. An SQL_C_DOUBLE should be a G_FLOAT. An SQL_C_FLOAT should be a F_FLOAT. For example, if you call SQLGetData asking for a SQL_C_FLOAT, you should get a VMS F_FLOAT back.

The ODBC-ODBC Bridge converts floats and doubles on the remote machine to the local machine format.
