Contains the measurement unit for a quantity and a precision that
specifies the number of digits after the decimal point for decimal quantities.

## Structure

`OrderQuantityUnit`

## Fields

| Name | Type | Tags | Description | Getter | Setter |
| --- | --- | --- | --- | --- | --- |
| `measurementUnit` | [`?MeasurementUnit`](../../doc/models/measurement-unit.md) | Optional | Represents a unit of measurement to use with a quantity, such as ounces or inches. Exactly one of the following fields are required: `custom_unit`, `area_unit`, `length_unit`, `volume_unit`, and `weight_unit`. | getMeasurementUnit(): ?MeasurementUnit | setMeasurementUnit(?MeasurementUnit measurementUnit): void |
| `precision` | `?int` | Optional | For non-integer quantities, represents the number of digits after the decimal point that are recorded for this quantity. For example, a precision of 1 allows quantities such as `"1.0"` and `"1.1"`, but not `"1.01"`. Min: 0. Max: 5. | getPrecision(): ?int | setPrecision(?int precision): void |
| `catalogObjectId` | `?string` | Optional | The catalog object ID referencing the [CatalogMeasurementUnit](entity:CatalogMeasurementUnit). This field is set when this is a catalog-backed measurement unit. | getCatalogObjectId(): ?string | setCatalogObjectId(?string catalogObjectId): void |
| `catalogVersion` | `?int` | Optional | The version of the catalog object that this measurement unit references. This field is set when this is a catalog-backed measurement unit. | getCatalogVersion(): ?int | setCatalogVersion(?int catalogVersion): void |
