ldiv
Description:
Include:
Prototype:
Calculates the quotient and remainder of two long integers.
<stdlib.h>
ldiv_t ldiv(long numer , long denom );
Arguments:
numer
denom
numerator
denominator
Return Value:
Remarks:
Example:
? 2008 Microchip Technology Inc.
Returns the quotient and the remainder.
The returned quotient will have the same sign as the numerator divided
by the denominator. The sign for the remainder will be such that the
quotient times the denominator plus the remainder will equal the
numerator (quot * denom + rem = numer). If the denominator is zero,
the behavior is undefined.
