Arguments

:: (ERIntApprox ira, DomainIntBox box varid ira, DomainBoxMappable box box varid ira ira) 
=> [(box, ira)]

the equations; each equation has coefficients of linear terms + constant term

-> box

the domain of the variables

-> ira

an upper bound on the size of an acceptable solution box

-> Maybe box

A box containing at least one solution within the domain; Nothing if there is no solution.
