Case considered superfluous.

A heavy-duty followup to the HP-18C. This unit has about 8K of RAM with about 6700 bytes available to the user for equation storage and cash flow calculations. While primarily a financial calculator, a little digging around will turn up some scientific functions not normally found in the financial world, including trig functions (circular and hyperbolic), angular conversions (degrees/radians, polar/rectangular), probability functions and unit conversions.

The HP-19BII differs only in including an RPN option for calculations. Neither calculator is programmable, but you can store an equation for the Solver to work on.
