RTOS/CC2640R2F: [BUG]-- UartLog display float variable as 0.0000 using %f as format

Tool/software: TI-RTOS

example project: project zero, i2chdc2010(simplelink sensor and actuator plugin example)

copy Uartlog.c, Uartlog.h to project i2chdc2010 do display temperature and humidity using Uartlog

but the code does show any float data as 0.0000

        Log_info2("%.2f DegC(Temp), %.2f %%RH(Humidity)", g_actualTemp, g_actualHumity);

to show the data correctly have to do workaround as the following:

int     i_actualTemp   = 0;
int     i_actualHumity = 0;
i_actualTemp = g_actualTemp;
i_actualHumity = g_actualHumity;
Log_info4("%d.%2d DegC(Temp), %d.%2d %%RH(Humidity)", g_actualTemp, (g_actualTemp - i_actualTemp) * 100, g_actualHumity, (g_actualHumity - i_actualHumity) * 100);
