# "ComputedQuantity" (interpreter type)

Quantity derived by computation.

## Allowed FormsAllowed Forms

• Any natural-language quantity supported by "Quantity", or a computation yielding one.

## Restriction SpecificationsRestriction Specifications

•  Restricted["ComputedQuantity",{{choices1,…}}] one among choices Restricted["ComputedQuantity",unit] convert to unit Restricted["ComputedQuantity",quantityvariable] restrict to units compatible with the physical quantity of quantityvariable Restricted["ComputedQuantity",unit,max] a quantity below Quantity[max,unit] Restricted["ComputedQuantity",unit,{min,max}] a quantity between Quantity[min,unit] and Quantity[max,unit] Restricted["ComputedQuantity",unit,{min,max,s}] a quantity between Quantity[min,unit] and Quantity[max,unit] with step s Restricted["ComputedQuantity",quantityvariable,max] a quantity below Quantity[max,unit], with unit the canonical unit of quantityvariable
• The bounds min and max and step s can also be expressed as quantities.
