14. Exchange Key
During calculation, the calculator files the information
in different registers (or reserve): the numbers in the
“number” register (that we will call the “x” and “y” later)
and the sign of the operation in the sign register.

The key allows an exchange between the content
of the register “x” and content of the register “y”. Take

15. Factorial
The calculation of “n!” is made possible through the
second function of the “CE” .To calculate 3!, for example,
press”3” first, followed by 2ndF n! .
16. Random Numbers
A pseudo-random number with three significant
digits can be generated by pressing 2ndF RANDOM .
Random number generation is not possible when
binary/octal/ hexadecimal system mode is set.
17. Memory Calculations
The calculator contains a memory that the user can
use at any time. Three keys are allocated for the
management of this memory:
-key “ STO ”:puts the display number into the
memory.
-key ” RCL” :recall the content of the memory to the
display.
-key “ M+ ” :adds the displayed number to the
memory with this sum.

to be used in the following calculation.
The previous calculation result will not be recalled
after entering multiple instructions.

19. Time, Decimal and Sexagesimal Calculations
This calculator also makes it possible to convert an
angle from sexagesimal format (express in degrees,
minutes, seconds) into a decimal format in degrees (key
→DEG), and vice versa with the second function of the
key →DEG (marked by →D.MS). For example, the
conversion of 1.876543203 into degree, minute, second:

20. Coordinate Conversions
It may be of interests to convert between polar
coordinates(r, θ) and rectangular coordinates (x, y). To
perform the conversion, follow the steps below:
1. To input the coordinates to be converted, enter
the first coordinate(x or r), then the key a and the
second coordinate (y orθ) then key b .
2. Press 2ndF →xy for polar-rectangular
conversion, or 2ndF →rθ for rectangular-polar
conversion.
3. The first coordinate of the result is display, second
coordinate of the result is obtained with the key b .
Example (x,y)=1,2 into polar coordinates

21. Binary, Octal, Decimal and Hexadecimal
Operations (N-Base)
This calculator can perform the four basic arithmetic
operations, calculations with parentheses and memory
calculations using binary, decimal, and hexadecimal
numbers.
When performing calculations in each system, first
set the calculator in the desired mode before entering
numbers.
It can also perform conversions between numbers
