• The initial default number base setting when you enter the BASE-
N Mode is always decimal (DEC).
Inputting Values
In the BASE-N Mode, you can input values using the currently
selected number base.
•A Syntax ERROR occurs if you input values that are not allowed
for the currently selected number base (such as inputting 2 while
binary is selected).
•You cannot input fractional values or exponential values in the
BASE-N Mode. If a calculation produces a fractional value, the
decimal part is cut off.
Inputting Hexadecimal Values
Use the keys shown below to input the alphabetic letters (A, B, C, D,
E, F) required for hexadecimal values.

The allowable calculation range is narrower from binary (16 bits)
than it is for the other number systems (32 bits).
•A Math ERROR occurs when a calculation result is outside the
applicable range for the number system being used.
Specifying the Base during Input
The BASE-N Mode lets you override the current default number base
setting and input a particular value using a different base. When
inputting the value, press 13(BASE) c to display page two of
the BASE menu, and then press the number key that corresponds
to the base you want to specify.
Press this key: To specify this number base:
1(d) Decimal (Base 10)
2(h) Hexadecimal (Base 16)
3(b) Binary (Base 2)
4(o) Octal (Base 8)
