calculator

问题 I am building trying to build a calculator that calculates a monthly payment based on an interest rate when clicking on a button, I'm using basic javascript bootstrap. I have already been through some answers and questions ironed out some bugs but my calculator still won't produce a figure. Could someone help? The HTML: <div class="row text-muted"> <div class="col-md-5 col-md-offset-1 calc-input"> <h3>Purchase Price</h3> <div class="input-group"> <span class="input-group-addon">£</span>

问题 I have a set of HTML number inputs with ID's YXS, YSM, YMED I can get the values of each input, add them together, and display the result to #output. HOWEVER, it only works when entered in order YXS, YSM, YMED If i remove YSM so its blank, i only get YXS as a value output to #output. Im trying to work it, so what ever values are entered, they're either added together and displayed, or if only 1 value is entered, then that value is displayed to #output regardless of the order of input. Ive

问题 I'm making a calculator for android using kivy and it's almost done (cannot use java becasue python is the only language I know). The way it works is, the user inputs an expression and eval is used to evaluate that expressions. At the moment, in my app, the eval expression can contain numbers, mathematical operators (+, -, /, *) and most of the operators from math module (In short, it's a scientific calculator) and it works as intended. In future I'm planning on integrating matplotlib to add

问题 Hello everyone and thanks for helping me. I made this calculator in C# and i got one problem. When i add something like 5+5+5 it gives me correct result but when i want to substract more than two number and also divide or multiply more than two number i don't get correct result. Do you know what i am doing wrong, Thank you very much! using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using

问题 In batch, I have trouble doing more advanced calculations with set /a . Decimals won't work; for example set /a 5/2 only outputs 2 instead of 2.5 . Also batch can't handle large calculations. Is there a way to just make a temp file (like vbs) or call on another program (like calculator) to do the calculation and return it back to the batch file? 回答1: The program below as an example of a Batch-JScript hybrid script that allows to evaluate any JScript expression: @if (@CodeSection == @Batch)

问题 Alright, I'm doing this for a project and whenever I attempt to have it divide by zero or square root a negative number that program closes out. I've attempted to find something I can insert into the code to make it display a message and then prompt for the value again, but everything that I've tried inserting causes the program to close out instantly when I start it up. Here's the calculator without anything inserted to fix the crashes. import math def convertString(str): try: returnValue =

问题 I have an assignment which is to create a calculator program in Haskell. For example, users will be able to use the calculator by command lines like: >var cola =5; //define a random variable >cola*2+1; (print 11) >var pepsi = 10 >coca > pepsi; (print false) >def coke(x,y) = x+y; //define a random function >coke(cola,pepsi); (print 15) //and actually it's more complicated than above I have no clue how to program this in Haskell. All I can think of right now is to read the command line as a

问题 I am developing an application which the user taps on EditText , it displays the android calculator, so the user is able to do arithmetic operations. I would like to retrieve the final value when the user presses the equal button in the android calculator and display it. Is that possible using the standard android calculator? The code to open the calculator is the following: Intent intent = new Intent(); intent.setAction(Intent.ACTION_MAIN); intent.addCategory(Intent.CATEGORY_LAUNCHER);

问题 Closed . This question needs details or clarity. It is not currently accepting answers. Want to improve this question? Add details and clarify the problem by editing this post. Closed 3 years ago . I'm trying to learn how to calculate the logarithm base 10 of any numbers that I enter via scanf to my code. I figure that I could calculate the ln(a) a being the number input. I have a working code that calculates this; however now i just want to divide any numbers that my ln(a) code outputs by

问题 I have made this calculator program in Java. This works well only when two numbers are calculated at one time. That means to get the sum of 1+2+3 you have to go this way : press 1 press + press 2 press = press + press 3 press = and it calculates it as 6. But I want to program this so that I can get the answer by: press 1 press + press 2 press + press 3 press = but this gives the answer 5!!! How to code this so that it works like an ordinary calculator? Here is my code: import java.awt.*;
