*   `[min; max]` define the clamping range for the `inputs` data.
*   `inputs` values are quantized into the quantization range (
`[0; 2^num_bits - 1]` when `narrow_range` is false and `[1; 2^num_bits - 1]`
when it is true) and then de-quantized and output as floats in `[min; max]`
interval.
*   `num_bits` is the bitwidth of the quantization; between 2 and 16, inclusive.

Before quantization, `min` and `max` values are adjusted with the following
