Different data types :

int or signed int (2 bytes)      -32,768 to 32767

short int (1 byte)                     -128 to 127

long int (4 bytes)                    -2,147,483,648 to 2,147,483,647

Float (4 bytes)                         3.4E-38 to 3.4E+38

double (8 bytes)                      1.7E-308 to 1.7E+308
