Calculator 2K

Calculator2K contains large set of functions.

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.
