Calc - KLC

Use

The operation of the program is very simple and intuitive. When you start the program, a formulary is displayed with a pre-populated formula in the top line. This is also provided as a guide to the format in which to enter the input formula. Below are fields where you can enter custom values for up to three variables. These are entered into the formula by writing the appropriate letter. After pressing the "Calculate" button, the expression is calculated. In case of division by zero or incorrectly entered expressions with parentheses, a warning window is displayed. Although the result is displayed, it is incorrect. By checking the "Debug" option, the bottom of the form is replaced with information about the calculation. The first line contains the partially evaluated input formula - it is inserted after the variables, the sine function is calculated and all expressions in parentheses are evaluated. From here, the partially evaluated formula can be used for other processing (for example, to describe the values of the expression in parentheses). The line below shows the mathematical operators used to finally calculate the value of the formula from the line with the partially evaluated formula and the line of the last numbers used to do so. So here you can see how the program is still simplifying the input formula and taking it to the final stage, which is just addition/subtraction.
