Calculator Pro

About this app

Calculator Pro is an easy,accurate and instant scientific calculator.

** Important ** slide the keyboard to access other mathematical functions!
** Important ** This video describes the old version. The new version has all the features and adds others.

It also allows you to solve elaborate expressions, with arbitrary level of operations. Calculation accuracy is its true power which computing up to 100 significant digits.

When you're entering a calculation, you can switch from a function to another function with a simple swype thanks to the interchangeable keyboards. The operations are varied:
- Basic operations
- Exponentiation (also non-integer exponent)
- Square root and generic radicals
- Logarithms (any base)
- Trigonometric functions
- Trigonometric inverse functions
- Hyperbolic functions
- Modulus & factorial

Adjustable between 10 and 100 significant digits, precision allows to solve equations inside different areas. Very helpful for scholastic, scientific or working environment.

Calculated results are being saved on a results history and it also can be memorized as costants, so you can identify a specific value without remembering the exactly number.

This is a beta application then there's a high probability to find bugs or errors. I should therefore be grateful if you all report me by email these possible malfunctions.

Ratings and reviews

can't copy and paste, keyboard slide does not work in vertical position, appears to have a lag. (touch-response). not trying to be an A- hole its cool somebody made the app all props to them, but the program is super buggy.. you're better off with your OS calculator.. wouldn't it be counterintuitive for an app designed to make the experience more functionable, but simultaneously removed basic functions. in other words an app should never sacrifice, only make "more suffice"( I know that's an oxymoron)

This calculator program is capable of very high precision math including pi sine cosine and most any funcyion you would need. One improvement they can make would be to have the output as well as the imput span more than one line. (20 chars maybe)

calculator I've ever used. This goes to 100 accuracy, but 1*10000 it says 1E+4, even on 100 accuracy, fix that and I'll give 5/5, until it can do small calculations like that, a 4/5
