FX991MS Scientific Calculator 1.2.6

Features:

1. Easy editing of large expressions with a simple click on the clipboard.
2. Capability to display numbers as large as factorial of 5000 by scrolling down.
3. No need to use the shift key; additional functions are easily accessible by scrolling down.
4. Expressions are automatically added to history when you press "=".
5. Adjustable text size.
6. Customizable decimal places.
7. Support for expressions with up to 500 operands.
8. Ability to utilize Infinite Parentheses.

Functions:

1. Basic mathematical operations like division, addition, subtraction, multiplication, modulo, and factorial, among others.
2. Calculation of the nth root of a number.
3. Factorial calculation up to 5000.
4. Evaluation of logarithms with a decimal base.
5. Inclusion of trigonometric functions.
6. Number base conversion from 2 to 16.
7. Matrix operations for finding Inverse, Adjoint, cofactor, rank, and determinant. Matrix addition, multiplication, and subtraction are also supported.
8. Handling of large numbers for various calculations.
9. Calculations involving exponents with decimal powers.
10. Includes over 40 constants for reference.

Note:

• The expression ln(23)^2 will be evaluated as ln(23^2), where 23^2 is first calculated as 529 before evaluating ln(529). To prioritize evaluating ln(23) first, enclose it in parentheses as (ln(23))^2. Proper use of parentheses is crucial for obtaining expected results.

This scientific calculator is designed to simplify the editing of large expressions. It aims to address the challenges faced in engineering scenarios that involve repeated modifications to complex expressions. Noteworthy features include the ability to handle large numbers, such as calculating the factorial of 5000, and the convenience of not requiring the shift key.
