问题 I have the following Slicer in Power BI Desktop, where # of Clients is calculated as Count(Distinct(Fact.EHRTransaction.ClientFK)) in my data model: My goal is to calculate Percentage out of Total (13 639) and add it to this slicer as a Measure or another Column, like: Gender # of Clients Total Clients Unknown 2 0.00% Intersex 13 0.00% Transgender 18 0.00% Female 662 0.04% Male 832 0.05% (Not Recorded) 12 112 72.79% I tried adding the following Column: Percentage = 'FactEHRClinicalTransaction

问题 I am not good at Swift so I would like to know how to calculate the current time is between two times. I got the following response from the backend. {"workHours":"M-F 9:00 - 18:00"} How to get start (9:00) time, end (18:00) time from "M-F 11:00 - 20:00" response using regular expression and DateFormatter?(I am not sure it is the correct way to get Date object from this kind of string, if not please recommend the best way and experience) 回答1: You can use the following regex: "^\\w-\\w\\s{1}(\

问题 I have created a scientific calculator program. What my program does is take "label" which is the string inputted by the user using buttons and evaluate the expression. What my program does is, as soon as the equal button (button_eq) is clicked, it calls the splitLabel method which splits the label into an Arraylist of numbers and operators. It then calls brackets which searches for brackets within the ArrayList and completes sub calculations by calling the method calculate. However, before

问题 I have a script in which I subset my data according to some set time periods and wanted to subset all the records that had occurred in the last month. However if I try to subtract one month from today's date it yields an NA: > today <- Sys.Date() > today [1] "2017-03-29" > today - months(1) [1] NA I do have lubridate loaded but I think this calculation is being performed with base R. If I subtract 2 or more months it works fine: > today - months(2) [1] "2017-01-29" > today - months(3) [1]

问题 the user is able to enter either a number or a name into a cell. When i put a number, sumproduct is working fine, but when i want it to check if the name of a named range is inside the cell, it doesn't return anything. =SUMPRODUCT((Data!A:A=A7)*((Data!C:C=V7)+(Data!C:C=W7)),Data!H:H) Data!A:A is an accountnumber and Data!C:C is the countryID. Data!H:H is the sales that need to be added up. I have a few named ranges with number attached to them FirstRange: 4, 12, 15 SecondRange: 7, 38, 65 How

问题 How do I calculate the reflection vector to this problem? Using the formula r = v - 2 (v.n)n I can get the reflection when the object is sat on the x or y axis however when using this formula when it isnt seems to give strange results. Any help would be greatly appreciated. Example of the problem 回答1: The normal vector n needs to be normalized. In your example, n should be (1/sqrt(2), 1/sqrt(2)) . 来源： https://stackoverflow.com/questions/58699100/how-to-find-reflection-vector-when-the-object

问题 First, I give thanks to ksav and his help thus far. I'm a foreman for a landscaping company and it's my responsibility to fill out forms for each site and keep track of our man hours so we don't go over the allotted time. I'm trying to digitize the documents in Adobe so I can enter the times in the field on my phone without pen and paper and have a JavaScript code automatically calculate the hours on site in decimal format. Note: I will be using 24-hour time aka military time (13:00/1PM 16:40
