About Calculator APK
Table Of Contents
Description
basic calculator, scientific calculator and graphing calculator, it also allows you to DIY your own calculator.Sample expressions
simple expression: 1+2
variable evaluation: pi
function evaluation: sin(0)
variable definition: a=3.5
function definition: f(x)=x^2-1
parentheses: (1-x)^2
You can call the function by simple input f(xxx), for example, if you define a function `f(x,x1) = x + x1`, and if you input `f(2,3)`, the result will be `5`.
Predefined functions
Logarithms and power
sqrt(x): square root; x^0.5
curt(x): cube root; x^(1/3)
log(x), ln(x): natural logarithm
log10(x), lg(x): decimal logarithm
log(base,x): arbitrary base logarithm
Trigonometric - radians
sin(x), cos(x), tan(x)
asin(x), acos(x), atan(x)
Trigonometric - degrees
sind(x), cosd(x), tand(x)
asind(x), acosd(x), atand(x)
Hyperbolic
sinh(x), cosh(x), tanh(x)
asinh(x), acosh(x), atanh(x)
Other
gcd(x,y): greatest common divisor
comb(n,k): combinations
perm(n,k): permutations
min(x,y), max(x,y)
floor(x), ceil(x)
abs(x): absolute value
sign(x): signum
rnd(): random value from [0,1). rnd(max): random value from [0, max).
gamma(x): (x-1)!
mod(x,y): modulo
Complex numbers
i or j is the complex base. Example:
i*i
(1+i)^2
e^(i*pi)
Operators
+ - × ÷ basic arithmetic
^ power
! factorial
# modulo
√ square root
' first derivative
Tips
Parentheses: you may omit the leading or final parentheses, e.g. 1+2)(3+4 is valid.
Multiplication: you may omit the multiplication operator when unambiguous, e.g. 3π+2(1+2)
Expression continuation: starting a new expression with an operator auto-inserts ans, the result of the last expression.
Clear: use the Enter key to quickly erase the whole input line.
Scientific e notation: 1e3 is 1000.
Angles in degrees instead of radians: use either sind(90) or sin(90deg).
Use trackball Up/Down to navigate the history.
Derivative
It is possible to compute the first derivative of a function with one argument using the prime notation: log'(5).
The prime mark (quote) must appear immediately after the name of the function, and must be followed by open-parentheses.
The derivative may be plotted e.g. sqrt'(x).
To compute the derivative of an expression you must define the expression as a named function: E.g. f(x)=x^3+x^2+1, followed by f'(x).
Multi plot
To plot multiple functions on the same 2d graph, simply enter them on the same line separated by ";". E.g. x;x^2;2
Binary, octal, hexadecimal
You can enter values in binary, octal or hexadecimal by prefixing them with 0b, 0o or 0x respectively, such as:
binary: 0b1010
octal: 0o17
hexa: 0x100
if you want to display the result in binary, octal, hexadecimal, click the menu `DEC` in the calculator.

Questions & Answers
Q: What is an APK File?
A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.
Q: If I install an APK from this website, will I be able to update the app from the Play Store?
A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.
Q: Why ApkClean.net can guarantee APK 100% safe?
A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.
Q: What are Android App permissions?
A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
Don't hesitate to contact us if you have any questions or concerns.
