Detailed Description

An assumption about an unknown mathematical value.

Assumptions have a type and a sign. The type describes the type of the value – if it represents a number or something else, and what type of number is represented. The sign restricts the signedness of a number. The sign generally only applies the assumptions representing a number. The assumption class also includes max and min values, which however are not used anywhere yet.
