Factorial Calculator
Factorial calculator
The factorial calculator is used to determine the value of a non-negative integer number. It is a simple calculator that uses a particular program to execute the computation. It has a single text field and three controls; the ‘Calculate’, equal sign (=) and ‘X’ buttons. They are effective and execute different actions in the calculator. The first step is to enter the value of the non-integer number (n) in the blank text field. Click the ‘Calculate’ button or equal sign to perform the calculation. The result will be displayed below the two controls. The method used in performing the calculation will also be displayed in the bottom platform of the calculator.For example;
Determine the value of 3!Solution
Enter 3 in the blank text field and click the equal sign or the ‘Calculate’ button to initiate the calculation.The result will be; 720
Calculation;
6! = 1×2×3×4×5×6= 720
The factorial calculator cannot be used to determine the result of larger non negative integer numbers as it gives an infinity result.
Formula;
The factorial calculator uses particular formula in computing the values.N! = 1 x 2 x 3 x 4 x … x n
The factorial calculator is used to perform several calculations in the shortest time possible. However, it can only execute one calculation at a time the fact that there is only a single text field. If you want to determine the result of new non-negative integer numbers, you will use the ‘X’ button. It is the fastest way of resetting the calculator. It is used to erase all data of the previous calculations from the text fields. It uses a simple formula in determining different factorials. This calculator is effective and delivers accurate results based on the values entered in the text fields.
