long Long Integer Data Type
The keyword long may be applied to the int and double types. The
long int type declares an object to be of "plain" integral type. The
size (and representation) of a long int object is implementation-
defined; however, a long int is guaranteed to be the same or greater
in size than an int. Whether or not a "plain" long int is signed or
unsigned is implementation-defined. The type long float is an
archaic synonym for the type double, and is no longer supported by
MS-C. The long double type is synonymous with the double type.
Notes: In MS-C, the size of a long int object is four bytes and
"plain" long ints are signed. That is, long int is
equivalent to signed long int and its range of values is
-2147483648 to 2147483647, inclusive. A long float is
eight bytes in size and it uses IEEE floating-point
representation.
One of the keywords signed or unsigned may be used as a
prefix to long int, to identify the long integer as being
signed or unsigned, respectively.
If long is used without the keyword int or double, int is
assumed.
An integral constant with the suffix L (or l) is
interpreted as a long int constant, as is any integral
constant that is too big to be represented in an int.
The ANSI C Standard has dropped support for long float as
a synonym for double. Therefore, it is suggested you not
use this archaic type.
-------------------------------- Example ---------------------------------
long int value = 6;
long action_code = 'A';
long int bit_pattern = '\xAB';
long int counters[6];
long *pointer_to_long_int;
long int function();
value = (long int) 123.45;
value = (long) 123.45;
value = 1234567L;
value = 1234567l;
long double average = 345.67;
average = (long float) 1234;
