Expand description
The allocated version of NonNativeFieldVar
(introduced below)
Fields
limbs: Vec<FpGadget<BaseField>, Global>
The limbs, each of which is a BaseField gadget.
num_of_additions_over_normal_form: BaseField
Number of additions done over this gadget, using which the gadget decides when to reduce.
is_in_the_normal_form: bool
Whether the limb representation is the normal form (using only the bits specified in the parameters, and the representation is strictly within the range of TargetField).
