| intn | n-byte integer type |
Dirty
| Syntax |
| ||||||||||||||||||||||||||||||||||||
| Description | The intn (n-byte integer) types are machine-dependent types that occupy a specified number of bytes. By contrast, the int type is in principle a machine-independent and mathematical type (it overflows, however, when the value is too large or small, that is, when the value does not fit into 4 bytes).

| Example |
var counter1 : int1 % Range is -128 .. 127
var counter2 : int2 % Range is -32768 .. 32767
var counter4 : int4 % Range is -2147483648 .. 2147483647

| Details | In current implementations of Turing, the range of the int is -2147483647 to 2147483647, which means that the int4 type allows one more value, -2147483648. This extra value is used in int to represent the state of being initialized. The intn types allow use of all possible values that fit into n bytes and thereby cannot check for initialization. The intn types are like the C language types short int, int, and long int, except that the number of bytes occupied by the C types depends on the particular C compiler.
