HIPER CALC
HIGH PRECISION SCIENTIFIC CALCULATOR
VERSION 8.1.3
for Android
Copyright © 2014  2021, HiPER Development Studio
The calculator has up to 100 digits of significand and 9 digits of exponent. It detects repeating decimals and numbers in it 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
The multiline display can be turned on in tablets to show the complete history of calculations and to provide access the previous results.
The users can choose from several highquality themes.
The calculator has several 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 nominator and a denominator);

mixed numbers;

periodic numbers and their conversion to fractions;

unlimited number of braces;

operator priority;

repeated operations;

equations (with one or more variables, systems of equations);

variables and symbolic computation;

derivatives and integrals;

graphs of functions, equations and integral area, 3D graphs;

calculation details  extended information about a calculation like all complex roots, unit circle etc.;
