Blackulator

Blackulator - Much more than just a Black Calculator.

A Basic Guide:

1. A B C and D are constants that you can use to store any value.

Once you type "=", the result of the current calculation will be saved to "Ans". After that, you can type any of the four constants followed by "sto" and the value in Ans will get stored into the constant of your choice.

2. "mrc" can be used to clear the stored variables.

3. "clr" will clear the input as well as result screen without clearing out the saved values in "Ans" or any of the four constants.

4. "del" will clear out the last character / operation

5. "inv" = inverse - will change the trigonometric symbols to inverse trigonometric, exponent/power symbols to root symbols and logarithmic symbols to anti-logarithmic symbols.

6. "hyp" will give access to hyperbolic trigonometric symbols.

7. DEG/RAD can be used to switch between degree and radians for use in trigonometry.

Right now, its just a Scientific Calculator.

The upcoming features include but are not limited to the following:

1. Physics, Chemistry and other Scientific Constants like the plank's constant, gravitational constant, and so on will be added to the calculator for direct access to the constants.

2. Engineering Formulae will be added to the Calculator so that you can just enter the values of parameters one after another and have the calculator apply the formula including any applicable constants.

3. Unit Convertor - I will try to add a unit convertor functionality into this app as well.

4. Graph Plotter - This is far fetched for me right now, but if I am able to figure it out, I will definitely want to implement a graph plotter into my calculator app.

5. Any other feature that the app users may ask for and that I find myself capable of implementing.

I do not discourage giving a bad review if you face a problem but please don't forget to update your review once your problem is resolved.

If the app is crashing due to any reason, please let me of the event leading to a crash in the review or by an email.

As a single developer dedicating all his free time to app development, I would greatly appreciate a positive review.
