    buf.putFloat(12.3F);
    buf.putDouble(12.3D);

    // Reset position for reading
    buf.flip();

    // Retrieve the values
    char c = buf.getChar();
    short s = buf.getShort();
    int i = buf.getInt();
    long l = buf.getLong();
    float f = buf.getFloat();
    double d = buf.getDouble();
