Arduino Nano - MCP9803 Temperature Sensor Tutorial

MCP9803 High Accuracy Temperature Sensor ±0.5°C at +25°C I²C Mini Module. The MCP9803 comes with user-programmable registers that provide flexibility to the temperature sensing applications.
In this tutorial we have set up an Arduino Nano to MCP9803 I2C Mini Module. We will record changes in the temperature.

Hi,
I don't understand this part:
int temp = ((data[0] * 256) + data[1]) / 16.0;
if(temp > 2047)
{
temp -= 4096;
}
float cTemp = temp * 0.0625;
can you explain, pls?
