calculator

问题 I'm trying to add the dot functionality to my calculator but I have been struggling getting it to work. So far what it does is that adds the decimal point but then when I press another number what it does is add 0 regardless the number you pressed.. Example: user input 9 (dot operation/decimal) and then 5 = to 9.0 Which of course is totally incorrect. Finally, I'm posting specifically the dot function and the number 9 which are the ones that produce that answer. Header file.. int Method;

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I just wrote a simple calculator script in python, generally python should recognize the (-)minus,(*)multiplication,(/)divide sign by default but while considering this script it's fails to identify the signs.

问题 I'm trying to make a calculator. http://i.imgur.com/exQLj4m.png The user will press the number they would like to calculate followed by the operator all in one line e.g '1+1-2+5' then Java would convert that into something it can understand and get the answer. But when I try you use setText() on the TextPane where the answer will show, it doesn't put more numbers in it just changes to the specified number. When I press 1 it shows 1 but when I press 2 it doesn't show 12, it shows 2. Is there

问题 you are always such an incredible help to me ... but, Im really stumped here. http://canboria.co.za/PHP/CALCULATOR/bond.htm A basic bond/mortgage calculator that I have worked out using some online refs & a little modification. How can I make this script work out the details on page loading (i did try action onload but, didnt do the trick ... kept running a loop & times out) Ideally, I want to have that each time a value is altered, it should work out the REPAYMENT VALUE ... any help, ideas

问题 Using Java, and JavaFX, I made a Scientific Calculator, but it has a problem with clearing after the answers on the "Scientific" buttons. It clears after the +/-/ // equations, but not on like, square root, or tangent. For example: Say I did 1 + 1, then pressed = and got 2. If I pressed another number, it would clear first, not just add onto the number like this: 25 But like this: 5 And if I pressed +/-/ // button, it would clear the text area, too of course, so that the user could put in

问题 Hey, working on some categories and I've bumped up against a weird issue, im basically expanding on a calculator class to add some trig methods, and i am getting an incorrect value when i call the sin method in the return in the form of a double. i send a value of 100.7 to the method and it returns 0.168231, from what i can see the correct value should be = 0.939693 or there abouts. heres the code, I'm also attaching a link to the full project here: (thanks) http://files.me.com/knyck2/svpfd4

问题 I'm a noob at Javascript, but I'm trying to implement something on my website where users can type a quantity, and the subtotal updates dynamically as they type. For example: if items are 10 dollars each, and a user types 5 in the text field I would like it to show $50 next to the text box. Pretty simple multiplication, but I don't know how to do it with Javascript. I think onKeyPress somehow? Thanks! 回答1: Assuming the following HTML: <input type="text" id="numberField"/> <span id="result"><

问题 I am currently taking an AP Computer Science class in my school and I ran into a little trouble with one of my projects! The project requires me to create a calculator that can evaluate an expression and then solve it. I have got most of that down, but I ran into a little trouble because my teacher asked me to use a while loop to continuously ask for input and display the answer, and I am stuck on that. To end the program the user has to type in "quit" and I can't use system.exit() or any

问题 Im trying to do the calculations using NSNumbers and keep track of the numbers that the user inputs.. The problem is that my app is not doing any calculations now after updated my code to append . the decimal value to value whenever the user press the dot button. Which can be found Append or Add the decimal point functionality in calculator. I have seen that the proper way to keep track of the inputs from the user and do the calculation is using the NSNumber but as I'm really new to Objective
