:mrdocs:

Return a number equal to the specified `value` (except for possible rounding) having the exponent equal to the exponent of the specified `exponent`. Rounding may occur when the exponent is greater than the quantum of `value`. E.g., `quantize(147e‐2_d32, 1e‐1_d32)` yields `15e‐1_d32`. In the opposite direction, if `exponent` is sufficiently less than the quantum of `value`, it may not be possible to construct the requested result, and if so, `NaN` is returned. E.g., `quantize(1234567e0_d32, 1e‐1_d32)` returns `NaN`. Return `value` quantized to the quantum of `exponent`.
