The MOD operator is the %. 

int n = 40;
if (n % 2 == 0) {
    cout << num << " é par";
}

Additionally see std::modulus

    Why the rest of the division operator is for operations with integer numbers and you are trying to do this with a float. In the case of floating numbers this operator makes no sense, the division of a float or double will leave no remains (although the result is not accurate due to how these types work, a float divided by a float or a int there’s always rest 0).

    And when the operand is less than the operator, ex: 1 % 2 != 0?

  • @Robson, think about mod as the rest of a division. If you split a number n for a value greater than n the entire division will be 0 and P rest (module) will be n.
