About this app

HiPER Scientific Calculator is a popular calculator with more than 35 million downloads and 200 000 five-star ratings.

The calculator has up to 100 digits of significand and 9 digits of exponent. It detects repeating decimals and numbers can be also entered as fractions or converted to fractions.

You can write expressions in a natural way and watch your calculations. The result is displayed as a number, simplified expression etc.

The calculator has several layouts suitable for various screen sizes:
- "pocket" for small devices
- "compact" for smartphones (in portrait and landscape orientation)
- "expanded" for tablets

A multiline display can be turned on in tablets to show the complete history of calculations and to provide access the previous results.

Users can choose from several high-quality themes.

The calculator has many functions, such as:
- basic arithmetic operations including percentage, modulo and negation;
- fractions (in the expression mode any expression including nested fractions can be entered as a numerator and a denominator);
- mixed numbers;
- periodic numbers and their conversion to fractions;
- unlimited number of braces;
- operator priority;
- repeated operations;
- equations
- variables and symbolic computation;
- derivatives and integrals;
- graphs of functions and integral area, 3D graphs;
- calculation details - extended information about a calculation like all complex roots, unit circle etc.;
- complex numbers
- conversion between rectangular and polar coordinates
- sums and products of sequences
- advanced number operations such as random numbers, combinations, permutations, common greatest divisor, etc.;
- trigonometric and hyperbolic functions;
- powers, roots, logarithms, etc.;
- degrees, minutes and seconds conversion;
- fixed point, scientific and engineering display format;
- display exponent as SI units prefix;
- memory operations with 10 extended memories;
- clipboard operations with various clipboard formats;
- result history;
- binary, octal and hexadecimal numeral systems;
- logical operations;
- bitwise shifts and rotations;

Ratings and reviews

This is by far the best calculator app ever!!! The team did an awesome job. Bugs are fixed quickly and questions are answered at no time! They even keep adding on more functionalities! The display is clean and logical. Even though it's packed with so many functions, you'll get used to it in no time! Best help document as well! I'm so happy and thankful! This is the only calculator you'll ever need.

Equals doesn't repeat the last operator and operand as it does in many simple calculators. In decimal (base 10) there is an 'Ans' 2nd option to work around that but it can't be applied to base 2, 8 or 16 (binary, octal or hexadecimal). Seems like a really basic thing to be able to repeat an operation on a previous answer in any number base.

Edit: Issue fixed after developer response, it was an MIUI issue that can be bypassed. I think something is really wrong with the color themes, and how they interact with the dark setting in the OS. Most themes are unusable (the text and button labels are not visible), and the rest are very low contrast, either the results screen or the buttons are super hard to read.

What's new

- New detail: Graph of limits
- New detail: Polar graph
- Decimal point in scientific and engineering notations can be shifted manually in details
- New settings: Display exponent in E notation
- Function parentheses can be deleted and inserted elsewhere
- Addition and subtraction can follow each other without an operand in between
