thx u advance
in programm of use ADC to read temp and disply it on LCD
what did mean the instruction
Code: 
    temp = (temp_res * VREF)/10.240;  // Calculate temperature in Celsuis
why division by 10.240 is necessry
 

It is just scaling the input to fit the temperature range at the same rate.
You could understand as a digital amplifier, giving the necessary gain/attenuation.
