* The minus sign of the mantissa is floating minus.
* The arithmatic key operation has the same sequence as the
mathematical equation, 6 pending operations are allowed and ( )
are up to continuous 15 levels.
* Mutual conversion and calculation in arithmetic among binary,
octal, decimal, and hexadecimal numbers.
* One independent accumulating memory.
* It is possible to convert and fix the display number system by the
* It is possible to specify decimal part
digits by the TAB key.
* Direct drive for LCD (1/3 prebias, 1/4
duty)
* Automatic power off (about 7.5
minutes)

The FE key also converts the display format of a displayed numerical value simultaneously with the
display format setting.
At the same time, the number of digits below the decimal point of the above modes follows the display
format assigned by the 2dnF and FE keys.
Further, in the same manner as the FE key, the conversion is also takes place simultaneously with the
display format setting.
When the number of digits is specified, the last digit displayed is a rounded number, and when there is no
specification of the number of digits, the last digit displayed is a cut number.
