How to print 64-bit data type (to UART console)?

In MCUXpresso-IDE, when I use CMSIS-DSP function: arm_dot_prod_q15() :

* I got a "q63_t" type data: result = 5 (I debug with break-point)

* But when I print with: 

            PRINTF("data: %X \r\n", result);  ===>  data: 430C0000       (It should be: data: 5)

 

So what is wrong, how to deal with "q63_t" data type? 

 

Thanks!

Jerry
