Antoine Pitrou commented on ARROW-9253:
---------------------------------------
It's to return true/false. Here is a possible API:
{code:c++}
/// Return true iff all values are multiples of factor
bool IntegersMultipleOf(const int64_t* values, int64_t length, int64_t factor);
/// Return true iff all non-null values are multiples of factor
bool IntegersMultipleOf(const int64_t* values, const uint8_t* null_bitmap,
int64_t length, int64_t factor);
{code}
> [C++] Add vectorized "IntegersMultipleOf" to arrow/util/int_util.h

> There are various places where we check whether an array of integers are all
> a multiple of another number (e.g. a multiple of 86400000 milliseconds per
> day). It would be better to factor out this data check into a reusable
> function similar to the {{CheckIntegersInRange}} function
