The US*1 provides the basic four math functions, and provides a constant all four functions, which is an unusual feature, even today. Most electronic calculators provide a constant only for multiplication and division. The US*1 uses algebraic logic, which is also rather uncommon in calculators of this time, with a separate "=" key used to calculate the result of an operation. The calculator provides a fully-floating decimal, with the decimal point always positioned to provide the maximum amount of accuracy within the eight-digit display capacity of the machine.
