NAMEldiv, lldiv - compute quotient and remainder of a long division
DESCRIPTIONThese 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.
RETURN VALUEThe 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 quotient and the remainder. The structure shall include the following members, in any order:
long long quot; /* Quotient */
long long rem; /* Remainder */
ERRORSNo errors are defined.
