Integral division
numer/denom ) as a structure of type div_t, ldiv_t or lldiv_t, which has two members: quot and rem.Parameters
- numer
- Numerator.
- denom
- Denominator.
Return Value
The result is returned by value in a structure defined in <cstdlib>, which has two members. For div_t, these are, in either order: |
|
Portability
In C, only theint version exists.For the
long int equivalent, see ldiv.For the
long long int equivalent, see lldiv.Example
|

Output:
38 div 5 => 7, remainder 3. |
Data races
Concurrently calling this function is safe, causing no data races.Exceptions (C++)
No-throw guarantee: this function throws no exceptions.If either part of the result cannot be represented, it causes undefined behavior.
