float fVal = 13.3892F;
printf("Float value ==> fVal :%f\n",fVal); 
long  lVal = * (long *) &fVal; 
printf("float as long ==> lVal: %ld\n", lVal);

That 3rd line takes the address of the float &fVal and what!?! multiplies it times a long pointer? or something?!?

cast the fVal to long and then assign that.

float fVal = 13.3892F;
printf("Float value ==> fVal :%f\n",fVal); 
long  lVal;
memcpy(&lVal, &fVal, sizeof(fVal));
printf("float as long ==> lVal: %ld\n", lVal);
