Casio fx-3650P is a programmable scientific calculator manufactured by Casio Computer Co., Ltd. It can store 12 digits for the mantissa and 2 digits for the exponent together with the expression each time when the "EXE" button is pressed. Also, the calculator can use the previous result to do calculations by pressing "Ans".[2][3]

The calculator is available in 6 modes:[4]
In this mode, if the result have both real and imaginary part, an "R↔I" symbol will appear at the top-right corner.[12]
This mode is for statistical calculation. For some input data, sum of squares of values (Σx2), sum of values (Σx), number of data (n), sample standard deviation (xσn-1) and population standard deviation (xσn) can be calculated.[15]
This mode is for statistical calculation and can be divided further into[16]
For some input ordered pairs, one of the below can be calculated.[19] (The availability differs from modes.[19])
Σx2, Σx, n, Σy2, Σy, Σxy, , xσn, xσn-1, , yσn, yσn-1, Regression coefficient A, Regression coefficient B, Correlation coefficient r, , , Σx3, Σx2y, Σx4, Regression coefficient C, 1and 2
The calculator can hold up to 4 programs with total capacity of 360 bt Program commands[20]:
Conditional jumps should be used in the syntax:
conditionstatement 1:statement 2
When condition is true, statement 1 is executed, then statement 2 is executed. If condition is false, statement 1 is skipped and statement 2 is executed.
E.g.: ...A=0A+1→B:C+5→D:... If A=0, both A+1→B and C+5→D is executed. If A≠0, only C+5→D is executed.
Unconditional jumps uses Goto and Lbl to operate.
When Goto n (where n is an integer in 0-9) is executed, the program will jump to Lbl n. Loops can be created with unconditional jumps.
The calculator will perform system check when shift, 7 and ON is pressed together. The system check have 3 parts.
Part 1: light check - All lights will be on when the system check is initiated, press shift then all lights will be off. Press shift to proceed. The next 2 screens have similar functions.
Part 2: display check - The dot matrix screen will display "24 PRG13" and the LCD screen will display "0000000000 00". Press shift to proceed. Then the display become "BBBBBBBBBB" and "1111111111 11". Then "CCCCCCCCCC" and "222222222 22" and so on up till "JJJJJJJJJJ""9999999999 99". Press shift to proceed to part 3.
Part 3: key check - Press shift, the LCD will display 1. Press alpha, up, down, left, right in order. The display will increase by 1 each time you press a button. Next, press MODE, prog, dx, x−1, x3, and so on up till Ans. When EXE is pressed, the display become "24 OK""13"(The display differs from version, the above is for version 4 of the calculator which is the latest version). Press ON to end the system check.
Warning: Using the following glitch may reset the calculator.
There is a glitch in the calculator.
Enter 1M+:10 as a program. 1M+:2 is also OK. Refer to the following table in this section.
0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | |

Note that (col) means the column header. For example Fix (col) at column 0 is Fix 0.
The table is the code table for the glitch. For example, the code 85 refers to A and 76 refers to Fix 7.
To translate the entered number to the characters:
Warning: If the code you enter begins with 2, the calculator will reset. Even if it is not the case, the calculator will also reset in some rare occasions if you use this glitch.
To restore the calculator back to a normal state without risking reset, do NOT switch off the calculator or press ON after using any glitches, but call Mode Clear (SHIFT->MODE->2). Programs and memory of variables will be preserved, the calculator will be reset back to COMP mode + Degree mode, however.
