1. An electronic calculator comprising: keyboard input means including a plurality of alphabetic, numeric, and function keys for entering numeric data and alphameric statements into the calculator, at least one of said plurality of keys being operative for entering a base ten exponentiation function into the calculator; memory means including a plurality of program storage registers for storing alphameric statements entered from said keyboard input means and a plurality of data storage registers for storing numeric data entered from said keyboard input means; processing means, coupled to said keyboard input means and memory means, for processing alphameric statements entered into the calculator and stored in said memory means to perform selected functions; and output means, coupled to said processing means, for providing a visual indication of selected alphameric information; said processing means being operative, following entry from said keyboard input means of a base ten exponentiation function, including specification of an argument in the form of an arithmetic expression, for computing the numeric result of that arithmetic expression, for raising the number ten to the power represented by the computed numeric result of that arithmetic expression to obtain an exponentiation result, and for causing said output means to indicate that exponentiation result to the user.
