Base
mode, select

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.

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.
