Range of Numbers

The 36-bit word size determines the range of numbers that can be represented in hexadecimal (9 digits), octal (12 digits), and binary bases (36 digits), and the range of decimal numbers (11 digits) that can be converted to these other bases.

When you key in numbers, the calculator will not accept more than the maximum number of digits for each base. For example, if you attempt to key in a 10–digit hexadecimal number, digit entry halts and the ¤annunciator appears.

If a number entered in decimal base is outside the range given above, then it produces the message !  in the other base modes. In RPN mode, the original decimal value of any too–big number is used in calculations. Any operation that results in a number outside the range given above causes OVERFLOW to be briefly displayed. The display then shows the largest positive or negative integer representable in the current base. In ALG mode, any operation (except +/– in the entry line but not in a variable prompt) using ! displays the ¤annunciator.
