Floating variable are not being recognised during debug and in launch phase

Part Number: LAUNCHXL-CC26X2R1

Tool/software:

Dear TI Family, 

I'm using TI Launchpad CC2652R1 board, and i using ADC module to input an value, during conversion process it is not considering float. During debug it says the float unknown and after loading the code, it is not recognised or throwing up garbage value.

Thanks for the replies! Regards, Siva
