why integer range between -327680to+32767..

Answer / jim

Question is in error! It should read -32768 to 32767.

An unsigned 16-bit value ranges from 0...65535.
In Hex 0...FFFF

A signed 16-bit value ranges from -32768 ... 32767
In hex 8000...7FFF

Just as 0 is 0, 1 is 1, 7FFF is 32767, FFFF is -1,
8000 is -32768.

So...
8000 FFFE FFFF 0 0001 0002 7FFF
-32768 -2 -1 0 1 2 32767
