This section describes functions for performing integer division. These
functions are redundant in the GNU C library, since in GNU C the `/'
operator always rounds towards zero. But in other C implementations,
`/' may round differently with negative arguments.
ldiv are useful because they specify how to round the quotient:
towards zero. The remainder has the same sign as the numerator.
These functions are specified to return a result r such that the value
r.quot*denominator + r.rem equals
To use these facilities, you should include the header file `stdlib.h' in your program.
divfunction. It has the following members:
divcomputes the quotient and remainder from the division of numerator by denominator, returning the result in a structure of type
If the result cannot be represented (as in a division by zero), the behavior is undefined.
Here is an example, albeit not a very useful one.
div_t result; result = div (20, -6);
ldivfunction. It has the following members:
long int quot
long int rem
(This is identical to
div_t except that the components are of
long int rather than
ldivfunction is similar to
div, except that the arguments are of type
long intand the result is returned as a structure of type
