ldiv
Declaration:
ldiv_t
ldiv
(long
numerator,
long
denominator
)
Category(ies):
Utilities
Description:
Computes the quotient and remainder of the division of the numerator by
the denominator. If the division is inexact, the resulting quotient is the
integer of lesser magnitude that is the nearest to the algebraic quotient. If
the result can be represented, then:
numerator
= quot *
denominator
+ rem
Inputs:
numerator
— Numerator.
denominator
— Denominator.
Outputs:
A structure (ldiv_t) whose elements are quot (quotient) and rem
(remainder) as defined above.
Assumptions:
None
Side Effects:
None
Availability:
In the jump table on AMS 2.04 and higher.
Always available in the AMS library.

Example:
The following code fragment will run on any version of AMS since it forces
the
ldiv
routine from the AMS library to be linked in.
include "tiams.h"
#undef ldiv
ldiv_t ldiv( long, long );
.
.
.
long num, denom;
ldiv_t ldt;
.
.
.
ldt = div( num, denom );
