DEC as the default number base.
Integer results are displayed
according to the Base mode.
Fractional and floating-point results
are always displayed in decimal form.

2. Calculate 0b10+0hF+10.
To enter a binary or hex number, you
must use the 0b or 0h prefix (zero and
the letter B or H). Otherwise, the entry
is treated as a decimal number.

When Base = HEX or BIN, the magnitude
of a result is restricted to certain size
limitations. Refer to page 346.

Preview of Number Bases
Calculate 10 binary (base 2) + F hexadecimal (base 16) + 10 decimal (base 10). Then,
use the
4 operator to convert an integer from one base to another. Finally, see how
changing the Base mode affects the displayed results.
Results use the 0b
or 0h prefix to
identify the base.
Important: The 0b or 0h
prefix is a zero, not the letter
O, followed by B or H.
