Description
Calculator!! has the following additional functionality compared with most available calculators:
- Shows the expression as you enter and keeps a history of your calculations (Swipe up on the screen to access the history.)
- Capability of performing fraction manipulations and converting between different formats (proper, improper, and mixed fractions) and seamless integration of fraction, integer, and decimal manipulations.
- Capability of inputting degrees, minutes, and seconds for angles and converting between degrees-minutes-seconds format and decimal format.
- Capability of calculating permutation, combination, Least Common Multiple (LCM), and Greatest Common Divisor (GCD).
- Quadratic and system of two linear equations solver
- Rectangular to polar and polar to rectangular coordinate conversion (extremely useful for phasor calculations for electrical engineers)
- Throws a set of dice (choice of 1 die to 4 dice)
- Backspace to delete last digit entered.
- Tip Calculator
- Geometry Calculator
- The left pane scrolls to reveal more functionality without a need to switch modes. The digits and most common operations are always visible and the less common operations can be revealed by scrolling the left half of the screen.
- Sinusoidal functions can be calculated for angles in units of degrees, radians, or gradians.
- Showing the content of memory on MR button, as long as it fits.
Calculator!! is an ongoing project and we are working on more features and functions to be added to every update of the app.
You are going to love the simplicity of the user interface and you will get used to the extra functionality added to this product.

Ratings and Reviews
Weird calculations
I did 4.85-4.562 and got an answer of 0.279999999999999999
That makes the calculated very unreliable since I use calculations of degrees and minutes to several decimal places and continue calculations from one sum to the other without rounding or retuning from scratch.
In response to the app developer - my exams for navigation and ship stability require stupid levels of precision. If it doesn’t provide the exact number on a simple 3dp subtraction how can I have confidence in spherical trigonometry calculations? It seems like nothing and in the real world it is nothing but in my exams which will certify me to be a Master Mariner they need to be precise in calculation and then reasonable in final answer.
Developer Response ,
If you did 4.85-4.562, yes you may get 0.287999999. But can you please be more specific on when this makes the calculations unreliable? Can you please go on with the rest of your calculations and tell us where you will end up with an unreliable answer? The fact that calculator shows 4.85-4.562 = 0.287999999 is because of using floating point type. There is no precise representation of decimal number with floating point types in a computer. But still this should not cause you any unreliable answers. So please let us know where this leads into giving you a wrong answer at some point?
If you convert 0.287999999999 to degrees and minutes you will get 17' 16.8'', which is the same result as if you converted 0.288 to degrees and minutes.
