formula

问题 In Excel there's a function Rank Average (see documentation). I wish to do the same in PHP. Looking online, I find a lot of ranking solutions, but not a lot of those take duplicates into account and when they do, the result I get is not the same as Excel is giving me at all. It's very important it does though. Ideally, what I'd need is a function that requires a score and array to compare it with, and give me the rank for it. Example with some actual date from Excel: $array = array(5.80,6.00

问题 i need to find 1 22 333 sequence formula/equation. I write this code for getting number like that but i need to find equation of this sequence Code: for (int i = 1; i <= 9; i++) { for (int j = 0; j < i; j++) { Console.Write(i); } Console.Write("\n"); } With this code I get this results 1 22 333 4444 55555 666666 7777777 88888888 999999999 Also Latex code line should works for me to. I mean equation somethings like this for example: 回答1: From the sum of a geometric progression , the value of

问题 I would like to insert a calculation in Excel using Python. Generally it can be done by inserting a formula string into the relevant cell. However, if i need to calculate a formula multiple times for the whole column the formula must be updated for each individual cell. For example, if i need to calculate the sum of two cells, then for cell C(k) the computation would be A(k)+B(k). In excel it is possible to calculate C1=A1+B1 and then automatically expand the calculation by dragging the mouse

问题 I have 2 decimal fields: GrossSalary and Deductions. In the report, I created a formula field named NetSalary, which is: If Not IsNull({SalaryDetails.GrossAmount}) Then {SalaryDetails.GrossAmount} - {SalaryDetails.Deduction} When data is available the report runs correctly, but if not I get the following error A number, currency amount,date,time, or date-time is required here. Details:errorKind Error in File tempxxxxxxxxx.rpt: Error in formula NetAmount: 'If Not IsNull({SalaryDetails

问题 My apologies if this is the wrong site for this problem, as it is more math-related than programming. I am trying to write a series of 7 page links, in a Google-esque fashion. Essentially, it will be 7 numbers, s to ( s + 6), where s is my starting value. I am having trouble calculating my starting value, given a limited amount of information. In advance, I know the maximum value in the series, this is variable, but it is always greater than 7. In my formula-writing attempts, I have been

问题 My VBA code is Function yEval(entry As String) yEval = Evaluate(entry) Application.Volatile End Function in Sheet1 in cell f4 i have formula =yEval(Sheet2!E19) cell d4 on sheet1 contains number 12 Sheet2!I19 contains string $Q if Sheet2!e19 has string INDIRECT("pries!"&Sheet2!I19&12) or INDIRECT("pries!"&Sheet2!I19&Sheet1!d4) or INDIRECT("pries!"&Sheet2!I19&"Sheet1!D"&row()+12) the formula return result from sheet pries!$Q12 if Sheet2!e19 has string INDIRECT("pries!"&Sheet2!I19&address(row()

问题 This question already has an answer here : matplotlib - write TeX on Qt form (1 answer) Closed 4 months ago . In my python program is a hierarchy of mathematical objects I've created, that represent mathematical formulae. For example, there's Collection , which is a series of Equations , which is a container of two Sums , Products , Quotients , Exponants or Logarithms , which are all establishments upon Figures , which can be numerical or variables. I need to display to the user, a step of

问题 s o o o o o o o o o o o o o o o o o o o o o o o e How can I calculate all possible paths, without using the same square twice, that a person could take to get from s to e ? I've created a grid array [[1,1]...[5,5]] but i dont know if that will work. I've also mapped possible squares, and tried to create a record and check and lots of junk. Any standard formula I could put to use here? 回答1: There are quite a few standard path finding algorhythms you could use for this. This is not related to

问题 Hm, this is language - agnostic, I would prefer doing it in C# or F#, but I'm more interested this time in the question "how would that work anyway". What I want to accomplish ist: a) I want to LEARN it - it's about my ego this time, it's for a fun project where I want to show myself that I'm a really good at this stuff b) I know a tiny little bit about EBNF (although I don't know yet, how operator precedence works in EBNF - Irony.NET does it right, I checked the examples, but this is a bit

问题 Basically, I have a context where I can't programatically tint an image, though I can change it's alpha value. With some experimentation, I've found that I can layer a red, blue, and green version of the image, with specific alpha values, to produce a wide range of colors. However, I am wondering if it's possible to achieve a true RGB representation through this method? If so, what is the formula for converting an RGB value into different alpha values for the red, blue, and green layers. 回答1:
