# Description

Xzfracal is designed to handle many complex mathematical expressions involving rational numbers with ease and precision. The followings are samples of problems that can be solved easily and accurately with Xzfracal:

- Conversion between fractions and repeating decimals.

- Complex arithmetic of fractions, mixed fractions, and (repeating) decimals.

- Comparison of fractions, mixed fractions, and (repeating) decimals.

- Greatest common divisors and least common multiples of integers.

- Integer and modulo divisions of integers.

- Optimal rational approximation.

- Factorial, combination, and permutation.

- Polynomial operations: addition, subtraction, multiplication, division, power, composition, evaluation.

- Matrix operations: addition, subtraction, multiplication, trace, determinant, transpose, inverse.

- System of linear equations.

Xzfracal computes the EXACT answers to all supported operations on integers and fractions provided there is enough memory and time to complete the computations.

Xzfracal is specifically designed to accept fractions, mixed fractions and repeating decimals in the most natural and user-friendly manner. The output format is very flexible and can be configured in many ways.

Xzfracal saves answers in a history stack, users can reuse any previous result in a new expression.

Xzfracal is 100% free, user-friendly and safe: It does NOT rely on ad in any manner (no distractive and potentially dangerous add-ons)! It does NOT query/collect/store/transmit user info in any manner!

Xzfracal is also available free online. Please be aware that exact answers to complex problems tend to require extensive resources (memory, computing power, and time), the algorithms used by Xzfracal eventually stop and produce exact answers, provided it is given enough memory and time.

I love it, but... Gives exact answers, but keyboard is a bit squished. Otherwise good.

Inez Yarbough

Sucks If there was a rating for 0 this would be it. When I was doing my homework I was really relying on this to work how i wanted it to. But I'm disappointed again. I can't find not one app that can help me these days. If your going to make an app make it from everyone's perspective. That's all I have to say.😲😲😲👅👅😢😢

Display the answer in mixed, simplified or decimal number form just pressing the fraction button.

Find the least common multiple and the greatest common divisor of two integers. It is almost a scientific calculator.

• Convert decimal number to fraction and fraction to decimal number. 1.4 becomes 1/2/5 or 7/5, 5/2 becomes 2.5 or 2/1/2.

• Simplify a fraction. 485/25 becomes 97/5 or 19/2/5 or convert to decimal 19.4

• Enter decimal, mixed fractions and fractios in a single calculation. Example 1/4 + 1/2/2 + 24 * 3 = 297/4

• Get the raise power of a fraction. Example 5/3^3 = 125/27

• Get the inverse of a fraction 5/4^-1 = 4/5

• Use parentheses for the order of precedence

Make fractions fun again!

You never have to look for a basic calculator again as long as you have your phone.

With the calculator you can:

• Add, subtract, multiply, divide and simplify fractions.

• Enter multiple values before solving, for example 1/2 + 1/4 + 1/8 = 7/8.

• Enter mixed integer and fraction values, for example (2 1/2) + (1 1/4) + 1/8 + 3 = (6 7/8).

• Mix decimal and fractions in a calculation, for example 5.25 + 2 1/2 = 7 3/4. All calculation results are expressed as fractions.

• Convert a fraction to a decimal number and a decimal number to a fraction. 5.25 becomes (5 1/4) or (5 25/100). (5 5/8) becomes 5.625.

• Display a history of your work or your math homework.

• Simply a fraction or a ratio, for example 27/36 becomes 3/4 and then convert to 0.75 or 75/100.

• Master fractions and make peace with whole numbers, denominators, numerators, quotients, division with remainders, and ratios.

• Find lowest common denominator by simply adding two fractions.

• Divide and see quotient with remainder in lowest fractional form.

• Compare fractions. Take the difference between two fractions to learn which one is bigger.

• Work with improper fractions.

• Work with negative fractions or numbers.

## scientific calculator

NHN-1 is a free advanced engineering and scientific calculator with a transparent widget that has fractions and percentage:

•A resizeable widget with arithmetic, percentage button, and fractions.

•Expression (formula) based input.

•Fraction input and output with conversion to proper fraction, mixed fraction and decimal. Even the quadratic or cubic root functions, for instance, will return fractions when the answer can be written as a fraction.

•Full history with buttons that load old results, in case you need to start over from a previous point.

•Unlimited memory slots that can be named and are always displayed on screen.

•Multiple input fields except on small phones. This let's you do short side calculations without losing your place.

•Pre-packaged functions for quadratic equations as well as many geometric formulae.

•Buttons that store user defined functions that are created by binding an argument to a binary operator.

•Visualization of multivalued complex functions (roots, inverse trigonometric, logarithm)

•Visualization of quadratic and cubic functions

•Visualization of angles returned from inverse trigonometric functions.

•Complex numbers are very easy to work with, and all functions work with complex numbers where they are defined (inverse hyperbolic cosine, for instance).

•There is a fourth layout for small phones that is not shown in the screen shots.

•A unit conversion utility that lets you build arbitrary composite units. Conversion factors are written to the history, so you can bind the factor with multiplication to do the same conversion many times.

The layouts are designed to be ergonomic for each of four device sizes in portrait and landscape. Here are some examples of what we've done to make the calculator easy and speedy to work with:

•On small tablets in landscape, the keys are split so you can operate the calculator with two thumbs.

•On small phones, the numeric keypad is right under your thumb when holding the device with one hand.

•Square root, square, inverse and negation are all close to the numeric keypad.

•On small tablets, the long "NHN-1" button is a gesture recognizer that lets you scroll the six input fields with your left thumb. That way you don't have to let go of the device with your right hand to click an input field.
