calculation

问题 I wish to take the value of an HTML string contained within <bdi> tags - perform a calculation on it - and output the results in a separate <bdi> string, dependent on which input is selected on-page. The source <bdi> value changes dynamically based on user interaction, but I want to know if what I'm asking is feasible and a rough guide on how to achieve it? Screenshot to illustrate the user elements: In the DOM, the source value is nested in the below tag: <li class="grand_total"> <span class

问题 I tried to build a function that calculates a binary number stored in a string into a decimal number stored in a long long . I'm thinking that my code should work but it doesn't. In this example for the binary number 101110111 the decimal number is 375 . But my output is completely confusing. Here is my code: #include <string> #include <stdio.h> #include <math.h> #include <iostream> #include <string.h> int main() { std::string stringNumber = "101110111"; const char *array = stringNumber.c_str

问题 I have a workbook with a lot of different formulas and I have one worksheet in it called Map, that I need to not auto calculate, every time I enter new data into a different worksheet. I have the following VBA code below on this worksheet. The problem is I need to manually go to the Developer tab, Properties, EnableCalculation, and select False. When I do it this way, the code works perfectly. However when I close and re-open the workbook, the EnableCalculation in the Properties, has been

问题 I am stuck, I need a small logic. I have two audio durations x = "00:00:07:18" y = "00:00:06:00" H : M: S: F Answer should be x + y = 00:00:13:18 H=hours S= seconds M=minutes F=frame My question is if x = "00:00:03:14" y = "00:00:13:18" answer should be x + y = **00:00:17:02** If the frame is greater than 30 it should increase 1 in second. I am using power shell. How can I determine the logic to calculate both of this? 回答1: Calculation of the first 3 parts ( hour:minute:second ), we can

问题 I was looking for a way to split my background in my flutter application using a wave, and I found this piece of code: Design a background from 2 images in flutter It works perfectly, and I could adapt it to my needs. The only thing I don't understand is that every time I open my keyboard and type something into an input field, the wave is recalculated. I thought if I used a StatelessWidget, that wouldn't happen. Does anyone have an idea how I can fix this problem? Thank you very much. 来源：

问题 I have a Python GUI which makes a simple calculation. Running the main file called gui.py opens up a graphical interface. I would like to open the graphical interface and automatically click on the Kjør beregning button . (it means "Run calculation" in norwegian). Button is defined the following way in gui.py : beregn_btn = tk.Button(av_beregn, text="Kjør beregning", font=bold, command=self._beregn) I'd like to add some code here to invoke calculation, if that is possible: So far without luck
