Introduction
One of the main features of CalcKit is the built-in Scientific Calculator. Built on top of the extensive math.js library, it is optimized for work, school and any kind of personal calculations. You can do anything from basic to advanced calculations.
Equations in the calculator can be entered using the built-in keyboard or by clicking the equation field and typing the equation manually using your hardware/software keyboard.
Buttons & Functions
Basic Buttons
0 1 2 3 4 5 6 7 8 9 – Standard Numbers
. – Decimal separator
± – Negate the number, enters ×(-1)
+ - × ÷ – Basic arithmetic operations, addition / subtraction / multiplication / division
( ) – Parentheses are used to group terms, for prioritizing equations, or passing arguments to functions
, – Used to separate arguments in a function (example: min(5, 10))
= – Calculate Equation
Orange Buttons

Settings – Show multiple settings for the calculator
2nd Function – Toggle the functions on the “Custom Buttons” rows
History – Show the latest 50 calculations (equation and result)
C – Clear the equation
DEL – Remove the last entered digit or function
Memory & Trigonometric Unit
DEG RAD GRAD – Change the trigonometric unit (degree/radian/gradian)
M+ – Add to Memory
M- – Subtract from Memory
MR – Memory Return (recall stored value)
MC – Memory Clear (clear stored value)
Programmer Buttons
0b 0o 0x – Binary / Octal / Hex Prefixes
A B C D E F – Hex Numbers
Examples:
0b 101101 – Binary Number (decimal 45)
0o 123456 – Octal Number (decimal 42798)
0x 123ABC – Hex Number (decimal 1194684)
Conversion Examples:
0 + 0b 101101 = 45
0x 0 + 1194684 = 0x123ABC

Edit Buttons
CalcKit’s Scientific Calculator gives you the possibility to customize the two top rows (portrait) or left rows (landscape).
By clicking the ⋮ button and then clicking Edit Buttons you will access the menu below, where you are able to change each button and it’s 2nd function.
1. Select the button that you want to edit
2. Select between Built-in and Custom button type
3. If you select Built-in you will see a drop-down list with pre-defined functions/constants that you can choose from.
4. If you select Custom you will see two input fields Name = Equation where you can enter your custom function or constant.
Here are some examples for Custom buttons:
Constants
Name = Value
pi = 3.1415926535
phi = 1.6180339887
e = 2.7182818284
Functions
Name = Formula
pow(x, y) = x ^ y
Fg(m) = m * 9.80665
log3(x) = log(x) / log(3)
After you finish editing the button, just click APPLY and the configuration will be saved right away.
