Static Activation Quantization

Problem

Quantize activations with a precomputed static scale: code = clamp(round(x/scale), qmin, qmax) applied element-wise. Return the list of integer codes; a zero scale yields zeros.

The signature is static_activation_quant(x, scale, qmin=-128, qmax=127).

Hint

Static scales are calibrated once and reused, so values saturate at qmin/qmax.

Test cases

case 1

in: [[1,-1],0.01,-128,127]

expected: [100,-100]

case 2

in: [[1000],1,-128,127]

expected: [127]

case 3

in: [[-1000],1,-128,127]

expected: [-128]

case 4

in: [[0.5],0.5,-8,7]

expected: [1]
