"This is a very basic programmable calculator with many shortcomings. Although there is a 9 digit display, the precision is limited to 5 digits because 3 are reserved for the exponent. There is no "power of" function. The reverse polish entry is limited by a two level stack, which is destroyed whenever a scientific function is used. The programming model is wasteful, for example constants require a start and end quote. Constants in programs must be integers."
