Programming[ edit ] Like many Casio calculators, the FXG includes a programming mode,  in addition to its display and graphing mode. It holds bytes of programming memory,  less than half a kilobyte. This is done by optimizing the number of steps a program has to fill a single unit of memory, instead of several. The calculator uses a tokenized programming language similar to the earlier FXP which is well suited to writing more complex programs, as memory efficiency is a priority. Tokenization is performed by using characters and symbols in place of long lines of code to minimize the amount of memory being used.

For the multiplicative inverse of a real number, divide 1 by the number. For example, the reciprocal of 5 is one fifth, and the reciprocal of 0. In mathematics and digital electronics, a binary number is a number expressed in the base-2 numeral system or binary numeral system, which uses only two symbols: typically "0" zero and "1" one.
The octal numeral system, or oct for short, is the base-8 number system, and uses the digits 0 to 7.
Octal numerals can be made from binary numerals by grouping consecutive binary digits into groups of three. For example, the binary representation for decimal 74 is Two zeroes can be added at the left: 00 1 , corresponding the octal digits 1 1 2, yielding the octal representation Programming Like many Casio calculators, the FXG includes a programming mode,  in addition to its display and graphing mode.
It holds bytes of programming memory,  less than half a kilobyte. This is done by optimizing the number of steps a program has to fill a single unit of memory, instead of several. Casio Computer Co. Its products include calculators, mobile phones, digital cameras, electronic musical instruments, and analogue and digital watches.
The calculator uses a tokenized programming language similar to the earlier FXP which is well suited to writing more complex programs, as memory efficiency is a priority. Tokenization is performed by using characters and symbols in place of long lines of code to minimize the amount of memory being used.
The User Manual programming catalog is written in these symbols,  allowing for lengthier programs to be written with less effort and less memory. The token is a reference that maps back to the sensitive data through a tokenization system.
The mapping from original data to a token uses methods which render tokens infeasible to reverse in the absence of the tokenization system, for example using tokens created from random numbers. The tokenization system must be secured and validated using security best practices applicable to sensitive data protection, secure storage, audit, authentication and authorization. The tokenization system provides data processing applications with the authority and interfaces to request tokens, or detokenize back to sensitive data.
The calculator has 26 numeric memories as standard. Additional memories can be created by reducing the number of bytes available for programs. Using this facility allows a total of 78 memories maximum. Graphing The calculator has a built in graphing feature which is unique to its model. The calculator can display either built-in graphs that are already programmed or display a user defined graph. When set into character mode the calculator can display up to sixteen characters on each of its eight display lines.
Exterior A black casing surrounds the calculator along with a metal panel implemented on the rear; a large plastic screen protects the LCD display window as well. Keys are labeled and printed on orange, green, blue, red, and black malleable buttons.
It has an approximate mass of The calculator does not accept an AC adapter and only uses batteries. The average battery life is around hours which is shorter in length compared to similar models. The lower keys have the traditional Casio layout. The EXE key would execute the sum on the keyboard. The Ans key could be used to represent the last answer; simple iterative functions could be built up. The upper keyboard has the main function keys. The power-on screen displays system mode, calculation mode, angle unit and rounding.
The original TI is itself an upgraded version of the TI Released in , it was one of the most popular graphing calculators for students. Although it does not include as many calculus functions, applications and programs can be downloaded from certain websites, or written on the calculator.
A scientific calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. They have completely replaced slide rules in traditional applications, and are widely used in both education and professional settings.
It has advanced functions suitable for applications in mathematics, linear algebra, statistical analysis, computer science and others.
The Casio FXP is a scientific calculator introduced in and sold until There are various ways in which calculators interpret keystrokes. These can be categorized into two main types: Programmable calculators are calculators that can automatically carry out a sequence of operations under control of a stored program, much like a computer.
A large x pixel LCD touch screen enables stylus-based operation. It was specifically designed for use by computer programmers, to assist in debugging. It is a member of the HP Voyager series of programmable calculators. All of them are capable of being programmed by means of sophisticated languages and tools including assembly language, Basic variants, and ports of programming languages such as C, as well as hosting add-ins which are compiled on a computer and then downloaded to the calculator.
Graphic calculators made by Casio include the touchscreen ClassPad as well as the models with traditional buttons which can be divided into two main generations listed below. Casio fxP is a programmable scientific calculator manufactured by Casio Computer Co. 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". Casio V. They were the successor models to the CFXG, the first Casio calculator with computer algebra system, or CAS, a program for symbolic manipulation of mathematical expressions. The calculators were discontinued and succeeded by the Casio ClassPad in
