SCal is Simple, Scientific, Smart Calculator that can be used by anyone (kids, student, teachers, professors, for fun, for work,..). It supports following features

Standard Operators     + -  *

Functional Operators     ! (Factorial) ^ (Exponent) % (Percentage) @ (Remainder)

Bitwise Operators     & (AND) | (OR) ~ (NOT) ^^ (Exclusive OR)

Shift Operators     > (RIGTH SHIFT)

Operator Precedence   PEMDOS  BODMAS ( ) ^ *  + -

Select Settings and Disable Precedence if you want input expression 2+3*4 to show 20.

Complex Numbers in the form of a+bi

Fraction Calculator e.g., ½ + ⅓ = ⅚

Results can be displayed in Hexadecimal, Octal, Binary , Fraction or Decimal

Current Expression can be saved using Send Or Enter Key.
 
Display Results in Local Language Format 

Set Precision for Decimal Numbers 

Results are computed after every click so need to press any Special Key to do computation - Real-time calculation

Digit Grouping : Comma (,) can be used to group digits without loosing meaning e.g,. 1,234,002 is treated as 1234002

Decimal Separator : Supports both . (Dot) and , (Comma) as Decimal Separator

Support Hexadecimal Numbers : Numbers starting with 0x or numbers containing digits A-F are treated as Hexadecimal Numbers.

Floating Point Hexadecimal Numbers are supported  0x3.a2p3

Angles can be specified in Radians or in Degrees.

Following functions are supported for real numbers

Trigonometric Functions  sin, cos, tan, asin, acos, atan

Hyperbolic Functions   sinh,cosh,tanh, asinh, acosh, atanh

Absolute Functions     abs

Complex Number Functions : Many real numbers functions and also complex number specific functions like abs, arg, norm, real, imag, conj.

Scientific constants supported are specified in App Keyboard.

Calculator Operates in Three Modes 

1. Constant Algebraic Expression Mode ±√∿⊻  
2. Polynomial Function Evaluation Mode f(x,..)  
3. Statistics Mode 📈  

Algebraic Expression Mode supports :
all operators, real numbers, hexadecimal numbers, floating point hexadecimal numbers, complex numbers and their related functions.

Polynomial Function Evaluation Supports maximum of five variables, variable name can be any character, for each character specified corresponding minimum, maximum and increment values are created with default value 1.

Graph are drawn for function with one variable. 

Multiple functions can be displayed in the same graph, each function should be separated by semicolon

Function Mode accepts constant expression apart from variables.

In Statistical Mode input data can be list of numbers separated by space, semicolon or comma. 
Following Functions are supported in Statistical mode
Sum, 
Mean, 
Product, 
LCM, 
GCD, 
Minimum, 
Maximum, 
Median, 
Mode, 
Standard Deviation,
Range,
Count,
Permutation
Combination,
Percentile,
Sort Data in ascending or in Descending Order.

Constant Expressions are allowed in Statistical Mode

Statistical Data can be represented in Line Graph, Pie Graph, Bar Graph, or graph can be disabled. 

Saved Expressions can be retrieved and added to current input expression using single click or double click. Single click appends result of the selected input expression while double click appends the actual selected expression.

Graphs can be saved as a PNG file and it's present under Download Directory.
Input Calculations and their results can be saved as an HTML file under Download Directory.

Labels X and Y Axis for Statistical Graphs can be specified in Settings.

User can use their own keyboard or Built In App Keyboard to enter expression, Use settings to use user keyboard. 

App Keyboard lists supported functions, constants, variable name, operators, hexadecimal letters for easy access.

Help screen contains examples.
