Arithmetic Operations
All functions are active in all bases (except nonshifted functions on
the top row keys).
All arithmetic operations in hexadecimal, octal, and binary base use
2’s complement arithmetic. When a division produces a remainder,
only the integer portion of the number is retained.
Example: Arithmetic in Hexadecimal, Octal, and Binary
Bases. Calculate 12F;, + E9Aq:
Keys: Display: Description:
(«] 0 Sets hexadecimal base.
12F E9A [=] FC9 Adds hexadecimal
numbers.
Calculate 77605 — 43264:
] 7711 Switches to octal base
(FC916 == 77118)
7760 (-] 4326 [=] 3432 Subtracts octal
numbers.
Calculate 100g + 54:
100 (] 5 (=] 14 Integer part of result.
Compare the previous result to the decimal division shown below:
100 (+] 5 (=] 5.0000 Converts all values in
the expression to Deci-
mal mode.
(=] 12.8000 Division of 6415 + 51.
(1008 = 6410).
(] 14 Integer portion of
12.8( in octal base.
