APP_LOG print float to serial

Hi, I'm using the APP_LOG function to print data to serial. Here's how i do it:

APP_LOG(TS_OFF, VLEVEL_L, "%d,%d,%d,%d,%d,", front_brake_pressure, rear_left_wheel_speed, rear_right_wheel_speed, front_left_wheel_speed, front_right_wheel_speed);
APP_LOG(TS_OFF, VLEVEL_L, "%d,%d,%d,%d,%f,%f,%f\n", inverter_fail, bms_fail, imd_fail, bspd_fail, latitude, longitude, altitude);
APP_LOG(TS_OFF, VLEVEL_L, "\n\r");

But for some reason I can only print int variables, why float doesn't work? And how can I print float variables aswell?

Thanks in advance!
