tmp275 and arduino uno

Using Arduino Sensors
1

hi,
I have a tmp275 sensor and arduino uno board.
my code to read the temperature is:

#include <Wire.h>

int tmp275Address = 0x48; // becouse I connect pins A0:A2 to ground

void setup(){
Serial.begin(9600);
Wire.begin();
}

void loop(){

float celsius = getTemperature();
Serial.print("Celsius: ");
Serial.println(celsius);
delay(3000);
}

float getTemperature(){
Wire.requestFrom(tmp275Address,2);

byte MSB = Wire.read();
byte LSB = Wire.read();

int TemperatureSum = ((MSB << 8) | LSB) >> 4;

float celsius = TemperatureSum*0.0625;
return celsius;
}

On the datasheet of sensor (http://www.ti.com/lit/ds/symlink/tmp275.pdf) is specified that the resolution of the sensor is 0,0625°C.
With my code I read a resolution of 0,5°C, but I would like 0,0625°C of resolution.
I'm not expert with the programmation and and I think that the problem is on the line:
"int TemperatureSum = ((MSB << 8) | LSB) >> 4; "
Can you help me?
thanks
P.S. the smiles is number eigth

if you post code using code tags (# button the 8 ) will appear normal.

give this a try and see if it makes sense.
int TemperatureSum = MSB *256 + LSB;

otherwise I think you need to read the datasheet as higher resolution might be set by writing to some register in the sensor.
(not familiar with this particular sensor)

Can you post the link to the datasheet?
Thanks,
