FX-991MS Scientific Calculator

Features:
1) Easy to edit large expressions. Just click anywhere on clipboard and edit your expression.
2) It can also show number as big as factorial of 5000. Just scroll down to see such big numbers.
3) No need to press shift. Just scroll down to use more functions.
4) When you press "=" expression will be added to history.
5) You can change text size.
6) You can fix decimal places.
7) You can write expressions with 500 operands.
8) You can use Infinite Parentheses

Functions:
1) Basic Math Operations such as divide,add,subtract,multiply,modulo,factorial etc
2) Can calculate nth root of a number
3) Can calculate factorial up to 5000
4) Can Evaluate log with decimal base
5) Trigonometric Functions
6) Number Base Conversion from 2 to 16
7) Matrix operations such as to find Inverse, Adjoint, cofactor,rank and determinant. Perform addition, multiplication and subtraction of Matrices
8) You can perform operations on large numbers
9) Can Calculate exponent with decimal power
10) 40+ constants
Note :
ln(23)^2 will be evaluated as ln(23^2) i.e. first 23^2 will evaluated which is 529 then ln(529) will be evaluated. If you want ln(23) should get evaluated first then write (ln(23))^2. Please use parentheses to get proper result otherwise you will get unexpected result.

This scientific calculator is made to make editing of large expressions easy. I have faced situation in my engineering where I have to write large expressions with little changes again and again. So I made this scientific calculator where you can easily edit and write large expressions. One more great feature of this scientific calculator is that you can deal with large numbers i.e. you can even calculate Factorial of 5000. One more thing you don't need to press shift this will save lot of time.

Please share and rate it 5 if you like it. I will regularly add more functions to it.
