Return a number equal to the specified `value` (except for possible rounding) having the specified `exponent`. Rounding may occur when `exponent` is greater than the quantum of `value`. E.g., `quantize(147e‐2_d32, ‐1)` 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, ‐1)` returns `NaN`. Behavior is undefined unless the `exponent` satisfies the following conditions * for `Decimal32` type: `‐101 <= exponent <= 90` * for `Decimal64` type: `‐398 <= exponent <= 369` * for `Decimal128` type: `‐6176 <= exponent <= 6111` Return `value` quantized to the specified `exponent`.
