Ans memory is not updated in case of error in evaluation.Variables. The calculator provides 9 memory varaibles. Values can be stored in these variables and they may be used later in expressions. The values remain stored in the computer in a file even after closing the application and retain the values the next time we run the application. The value stored in variables can be that of real numbers or co mplex numbers.SeriesWe may evaluate series such as sum of first ten natural numbers, or product of even numbers from 20 to 40. How to use. Just run the demo project.
To do this, download the file scientificcalculatordemo.zip. Unzip the file. Run the file scientificcalculatordemo/release/calculator. Enter any expression as stated earlier. Press = button, or hit the = or Enter key on the keyboard to see the answer. If the answer is lenghty scroll down the textbox to view the complete answer.To store values in variables and use them. Check the mem radio button.
We may directly add or subtract to the memory variables. Depending on whether store,add or subtract checkboxes are checked, values are stored to, added to or subtracted from the variables whose buttons are clicked. If none of check boxes on the memory variables-form are checked, a hit on a button in this form inserts corresponding variable to the expression. The memory variables may contain real values or complex values.To evaluate expressions containing trignometric functions.
To get the inverse functions to the expression click inv checkbox and then the button of the trignometric function whose inverse is required in the expression.To evaluate expressions containing series. Check the series radio button. Enter the lower value of the variable in the series expression in expression textbox and check Setlow and then I button. Similarly set the high value of the variable in the sries expression. The upper and lower limit of the variable have to be integers and upper limit should be greater than lower limit numerically. Now enter the expression containing the series expression and press = to view the result. For example, to find sum of first ten natural numbers:type 1 - Setlow - I; type 10 - Sethigh - I; type 'SΣI'-=;to view the answer 55 in value textbox.

At present, for all SΣ and Sπ that appear in a single expression, the range of variable will be same. With a further enhancement, we may get rid of this limitation.Android appHere is an android app that uses the same parser mentioned in this article:. The only difference is that the App implements the same parser in JS and uses PhoneGap.
