FUNCTION
<<atoll>>---convert a string to a long long integer
INDEX
atoll
ANSI_SYNOPSIS
#include <stdlib.h>
long long atoll(const char *<[str]>);
TRAD_SYNOPSIS
#include <stdlib.h>
long long atoll(<[str]>)
const char *<[str]>;
DESCRIPTION
The function <<atoll>> converts the initial portion of the string
pointed to by <<*<[str]>>> to a type <<long long>>. The call to
atoll(str) should be equivalent to strtoll(str, (char **)NULL, 10)
except that <<atoll>> doesn't detect errors.
RETURNS
The converted value.
PORTABILITY
<<atoll>> is ISO 9899 (C99) and POSIX 1003.1-2001 compatable.
No supporting OS subroutines are required.

ANSI_SYNOPSIS

DESCRIPTION
The <<llabs>> function computes the absolute value of the long long integer

The similar function <<labs>> uses and returns <<long>> rather than
<<long long>> values.
RETURNS
A nonnegative long long integer.

FUNCTION

lldiv
ANSI_SYNOPSIS

TRAD_SYNOPSIS

DESCRIPTION
Divide
@tex
$n/d$,
@end tex
@ifnottex
<[n]>/<[d]>,
@end ifnottex
returning quotient and remainder as two long long integers in a structure
<<lldiv_t>>.
RETURNS
The result is represented with the structure
. typedef struct
. {
. long long quot;
. long long rem;
. } lldiv_t;
where the <<quot>> field represents the quotient, and <<rem>> the
remainder. For nonzero <[d]>, if `<<<[r]> = ldiv(<[n]>,<[d]>);>>' then
<[n]> equals `<<<[r]>.rem + <[d]>*<[r]>.quot>>'.
To divide <<long>> rather than <<long long>> values, use the similar
function <<ldiv>>.
PORTABILITY
<<lldiv>> is ISO 9899 (C99) compatable.
No supporting OS subroutines are required.

* The ANSI standard says that |r.quot| <= |n/d|, where
* n/d is to be computed in infinite precision. In other
* words, we should always truncate the quotient towards
* 0, never -infinity.
*
* Machine division and remainer may work either way when
* one or both of n or d is negative. If only one is
* negative and r.quot has been truncated towards -inf,
* r.rem will have the same sign as denom and the opposite
* sign of num; if both are negative and r.quot has been
* truncated towards -inf, r.rem will be positive (will
* have the opposite sign of num). These are considered
* `wrong'.
*
* If both are num and denom are positive, r will always
* be positive.
*
* This all boils down to:
* if num >= 0, but r.rem < 0, we got the wrong answer.
* In that case, to get the right answer, add 1 to r.quot and
* subtract denom from r.rem.
