ldiv, lldiv - compute quotient and remainder of a long division
ldiv_t ldiv(long numer, long denom);
lldiv_t lldiv(long long numer, long long denom);
These functions shall compute the quotient and remainder of the division of the numerator
numer by the denominator denom. If the division is inexact, the resulting quotient is the
long integer (for the ldiv() function) or long long integer (for the lldiv() function) of
lesser magnitude that is the nearest to the algebraic quotient. If the result cannot be
represented, the behavior is undefined; otherwise, quot * denom+rem shall equal numer.
The ldiv() function shall return a structure of type ldiv_t, comprising both the quotient
and the remainder. The structure shall include the following members, in any order:
long quot; /* Quotient */
long rem; /* Remainder */
The lldiv() function shall return a structure of type lldiv_t, comprising both the quo-
tient and the remainder. The structure shall include the following members, in any order:
long long quot; /* Quotient */
long long rem; /* Remainder */
No errors are defined.
