It has all the usual log and trig (Deg, Rad and Grad) functions, including hyperbolic. It can work in decimal, hex, octal or binary, (integers only for other than decimal) It has accumulators for statistics sum, sum of squares, standard deviation, n!, it can calculate with complex numbers and generate random numbers. It also has a cube root function which is rather unusual for a scientific calc, I think. There is one memory register and the dynamic range is ±9.999999999e±99. The calculator forensic shows 8.9999998639 which doesn't match any of the calculators in the list at

Has anyone bought a new (used doesn't count) scientific calculator for less than that? If so, how much was it and what functions does it have?

Which dollar store chain?

What is the Mfr/Model info.

How about a pic?

For a dollar, I'll go find one if I can. This sets a new metric for features/dollar, I think.
