divCeil(
N num,
D denom);This function undergoes the same integer promotion rules as a built-in operator, except that we don't allow bool -> int promotion. This function is undefined if denom == 0. It is also undefined if the result type T is a signed type, num is std::numeric_limits<T>::min(), and denom is equal to -1 after conversion to the result type.
num/denom, rounded toward positive infinity.
