About FXCalc Scientific Calculator
FXCalc is an accurate formula scientific calculator with a modern look.
Enter a mathematical expression and use the equals button to evaluate it, carrying out calculations in sequence determined by common mathematics order of operations.
Note: The In-App purchase permission is for buying advanced optional features in the future, to support development of this app. The current features and some of the future features will always remain free.
The expressions and their results are stored in the calculation history. To go back and forward in history, use the up and down arrow buttons.
To start editing the displayed formula, use the left or right arrow button. When editing a formula, use these buttons or tap anywhere within the formula to move the caret.
To clear the current formula, use the AC button. When viewing a formula, you can also just start entering a new expression without clearing the old one.
To switch between the insert and replace modes, use the INS toggle button.
The calculation results can be displayed in different formats.
To display results in normal (fixed point) notation, use either Nor1, Nor2, or Fix buttons.
To display results in scientific (exponential) notation, use either Sci or Eng buttons.
To adjust the number of digits to display, long-press the button (except Nor2) then use the slider.
The angles (e.g. for trigonometric functions) can be expressed in either Degrees, Radians or Grads. To cycle between angle units, use the DRG button.
To access the hyperbolic and inverse trigonometric functions, use the hyp and inv toggle buttons.
Currently, two variables are available to use, additional variables will be added later.
The answer variable (Ans) is a special variable that contains the result of the last successful calculation. To recall it's value, use the Ans button.
The memory variable (M) is a general purpose variable with dedicated buttons
To set, recall and clear (set to zero) the memory variable, use the MS, MR and MC buttons.
To increase or decrease the value of the memory variable by the current value, use the M+ and M- buttons.
The display precision is limited to at most 12 decimal digits, the decimal exponent range is limited to [-99; 99].
Internally, the calculator uses IEEE 754 double precision floating point arithmetic, allowing representation of numbers with a decimal exponent range of [-308; 308] with 15–17 decimal digits precision.

Thank you so much for providing an amazing calculator with no ads. My only complaint is that I wish the font size was a tiny bit larger but other than that it's perfect!

If you developers put in the same functions as a hp prime or a hp 50g you could profit a lot. There is no good competidor app for this. Even wolfram, because doesnt works offline. Think on engineering students that need to solve 5x5 linear systems or work with vectors, polynomial regressions and interpolations. If you make a fancy hp prime app, I'm absolutely sure that I'll buy it!!!

I've been looking for a LSRL calculator(Least Squares Regression Line). Any chance that someone could make an app for one?! It would make me oh so happy!!

Polar to rectangular co-ordinate conversion and vice versa --- please incorporate this function... It is really helpful for complex algebra calculation...

It would be nice if one could apply functions (cox, sqrt, ...) to the current value - just like it was on my old TI-30.

Making degrees a default mode was a nice move. Decimal to fraction will be nice touch. Please look into it.

Do not download this app. I did a calculation using sin45 and it gave the wrong figure, which caused me to get something made, which didn't fit! Worse than utterly useless. Apparently the default is Radians unlike all other Scientific Calculators I've ever known including the fx series.

For trignometry it is rubbish...and if it cant help us in that then why it is a scientific calculator.

Some more themes would be appreciated. Like a more classic fx model. And the default model should be Deg. Anyways nice job.

I searched so many aps for a better scientific calculator. Usually i found that installed aps contains adds. And i am not satisfied at all. Also in other aps i found some irregular answers. Eg. If i want to know sin 30. For that i first type sin. I got an error instead of answer even i didn t type 30. But i aM happy to share that this ap have no such errors. It is just as like my scientific calculator

Letters & numbers are too small & its difficult to see properly (specially for those who have eye problems) plz remove that dot (.) From 0. Because it luks lyk 8 when working fast. it takes 3 seconds while opening the app. One more thing...maybe um missing it...where is % sign btw???

I've been trying to find a scientific calculator on here that looks good and has stuff that a scientific calculator has... It has been hard.. But I found it and it was this one... Even though it's not as high on the list as the other ones... This one is the best
