# Arithmetic Operations - HP -22S Owner's Manual

Scientific calculator.

When you are in the middle of a calculation, number(s) that are out-
side the conversion range are represented by the message

Arithmetic Operations

base-conversion range .

The arithmetic operations
G, B, 0,
and
G
can be performed in
any base. You can also use
'STO
I
and
'RCL
I
to store and recall non-
decimal numbers, and to do storage arithmetic.
All arithmetic operations use 2's Complement arithmetic. Operations
with hexadecimal, octal, or binary base use integers only. When a di-
vision produces a remainder, only the integer portion of the number is
retained.
If the result of an arithmetic operation in hexadecimal, octal, or binary
base cannot be represented in 36 bits, the HP-22S displays the over-
flow warning, followed by the largest (or smallest) number possible.
