Elementwise $a \cdot \log(other)$ with the $0 \cdot \log(0) = 0$ convention. Broadcasts and promotes as [`add`](./add.md#add).

**Returns:** the broadcast-shaped result at the promoted float dtype.

**Throws**

- `ClikaRT::Error`: (`INVALID_ARGUMENT`) when the operand shapes are not broadcast-compatible.
