Calculator 2K

Calculator2K contains large set of functions. Also, you can always add your own functions.

Comparison operations allow creating piecewise functions.

Supported by assigning a value to a variable (x ← 28), so you can use this value to other parts of the expression. Supported by characters of sums (∑) and products (∏).

You can calculate the value of the definite integral, or to plot functions.

Features:

* Creating your own functions,

* Using variables,

* History of computing,

* Calculating percent in formats 60+25% = 75 and 25%60 = 15,

* Function of cycle,

* Conditional expression,

* Enter numbers with the prefixes of decimal multipliers,

* Output of intermediate values calculation,

* Calculation of the definite integral,

* Plotting functions.

Example of creating piecewise functions:

G()←x1<-2:-4,x1<2:x1×2,4

The result of the function G(x1): for x1 less than -2 is -4, for -2 ≤ x1 <2 is x1 × 2, otherwise 4.
