libpq: PQexecParams, binaryFormat and float

["Sun, Way" <Way(dot)Sun(at)sciatl(dot)com>]

Hi,

I'm having trouble inserting a float into pg using binary format.

Hope someone on the list can help me point out what I'm doing wrong....

    float    loadavg;

    loadavg = htonl(1.23);

    paramValues[0] = (char *) &loadavg
    paramLengths[0] = sizeof(loadavg);
    paramFormats[0] = 1;       

    res = PQexecParams(conn,
                       "INSERT INTO cpu (loadavg) VALUES ($1::real)",
                       1,       
                       NULL,    
                       paramValues,
                       paramLengths,
                       paramFormats,
                       1);     

From psql, select returns the value as 1.20765e-38 instead of 1.23.....:(

Thanks

Way
