DDS output format and Complex multiplier

Hello,

I have to multiply a signal coming fro a DDS output with an other signal.

I see that the DDS output format is fix16_15 and the Complex Multiplier core input (channel B)  is fix16_0.

What fix16_15 and fix 16_0 mean ? Do I have to translate fix16_15 to fix16_0 to be compliant with the  Complex Multiplier input ?

Thank you.
