Access: public
Specifiers: staticBlueprintPureUFUNCTION
Description
Computes the arithmetic mean of an integer array as a float. Returns 0 for an empty array.
Caveats & Gotchas
- • The sum is accumulated as a float before dividing, which can lose precision for very large integer values (> ~16 million) where float32 cannot represent all int32 values exactly.
- • An empty array produces AverageValue of 0.0f with no error or indication — always check array length if 0 is a meaningful value in your domain.
