CCS/CC2650: Print float Value in console

Tool/software: Code Composer Studio

Hi, I am calculating a floating value and I want to print it in the CCS console, but when I did that the system just print a "f"

int conv;
float vi;
float vo;

vo = conv * 0.000034;
vi = (10.101/0.101)*vo;
System_printf("Voltaje\nRango 14 - 140\n%f\n\n",vi);
System_flush();
