Issue description
This PR addresses an issue with out-of-range values during scalar quantization. Previously, when quantizing data, values outside the calibration range could result in incorrect quantization.
Solution
The PR fixes this issue by introducing a clip operation in the quantization process. This operation ensures that quantized values are correctly bounded within the expected range, thus preventing out-of-range values from producing incorrect results.
Example
Result:
incorrect quantized values for the first and third entries, respectively, which are outside the calibration range.
After the PR:
The quantized values are correctly bounded and thus match the expected output.
