To enter a binary number, use the form:
0b binaryNumber (for example: 0b11100110 )
To enter a hexadecimal number, use the form:
0h hexadecimalNumber (for example: 0h89F2C )
If you enter a number without the 0b or 0h prefix, such as 11, it is
always treated as a decimal number. If you omit the 0h prefix on a
hexadecimal number containing A – F , all or part of the entry is
treated as a variable.
Use the 4 conversion operator.
integerExpression 4 Bin
integerExpression 4 Dec
integerExpression 4 Hex
For example, to convert 256
from decimal to binary:
256 4 Bin
To convert 101110 from binary
to hexadecimal:
0b101110 4 Hex
Instead of using 4, you can:
1. Use 3 (page 346) to set
the Base mode to the base
that you want to convert to.
2. From the Home screen, type
the number that you want to
convert (using the correct
prefix) and press ¸.
If Base mode = BIN:
If Base mode = HEX:
Entering and Converting Number Bases
Regardless of the Base mode, you must always use the

displayed.
Alternate Method for
Conversions
Binary number with up to 32 digits

For 4 , press 2 Ž . Also, you
can select base conversions
from the
MATH /Base menu.
For a binary or hex entry, you
must use the 0b or 0h prefix.
Results use the 0b or 0h
prefix to identify the base.
