rounding

问题 Is there any way to round up decimal value to its nearest 0.05 value in .Net? Ex: 7.125 -> 7.15 6.66 -> 6.7 If its now available can anyone provide me the algo? 回答1: How about: Math.Ceiling(myValue * 20) / 20 回答2: Use this: Math.Round(mydecimal / 0.05m, 0) * 0.05m; The same logic can be used in T-SQL: ROUND(@mydecimal / 0.05, 0) * 0.05 I prefer this approach to the selected answer simply because you can directly see the precision used. 回答3: Something like this should work for any step, not

问题 How can I round up a number to the second decimal place in python? For example: 0.022499999999999999 Should round up to 0.03 0.1111111111111000 Should round up to 0.12 If there is any value in the third decimal place, I want it to always round up leaving me 2 values behind the decimal point. 回答1: Python includes the round() function which lets you specify the number of digits you want. From the documentation: round(x[, n]) Return the floating point value x rounded to n digits after the

问题 I have a float number like 137.57667565656 but I would like to round it such that there are only two trailing digits after the decimal point like the new float number will be 137.58. I tried this so far: (Math.round((value*100)/100)).toFixed(2).toString(); But unfortunately, it rounds my value to 137.00. It adds the decimals places as zeroes, why? How can I achieve the above? 回答1: What did you expect? (value*100)/100 simply returns the original value of value , so Math.round((value*100)/100))

问题 I am not able to figure out how to get r to correctly show the head of my data. This is an assignment for Swirl, so I have to figure out how to write my code in a way that Swirl will accept as the answer. Swirl wants the final printout to look exactly like this: ## Pclass agecat Sex N survivors perc_survived ## <int> <fctr> <chr> <int> <int> <dbl> ## 1 Under 15 female 2 1 50.000000 ## 1 Under 15 male 3 3 100.000000 ## 1 15 to 50 female 70 68 97.142857 ## 1 15 to 50 male 72 32 44.444444 ## 1

问题 In the formula bar the data shows up as 69.849999999 and in the cell as 69.85 . I am trying to get that number in the formula bar as 69.85 . I tried Copy and Paste Values and almost everything else that I can think of. Even formatting the cell as a number with only two decimal places. Nothing is working. Any ideas? 回答1: Try: =ROUND(A1,2) then select, Copy, Paste Special, Values. 回答2: The following will radically change your data so use it with caution; possibly even on a backup copy until you

问题 I am beginner coder in web design so I have a fairly amateur question to ask. I have created a box of text but I don't know how to make the edges round rather than rectangular. I know that CSS functions on rectangular borders. If possible, I would also like to add a slight shadow beneath the box, I'm not sure how to implement this also. Here is my code specifically for the box section: #wrapper{ border: solid 1px #eeeeee; } "#wrapper" refers to a piece of php code in another document. Thank

问题 I'm having an issue with a query I wrote where for some reason the variable that I'm using to store a decimal value in returns 6 values after the decimal place (they're mostly 0). I have tried the following (and different combinations using Math.Round) with no luck. Sales = (from invhed in INVHEAD ... // Joins here orderby cust.State ascending select new Sale { InvoiceLine = inv.InvoiceLine, InvoiceNum = inv.InvoiceNum, ... NetPrice = Math.Round((inv.ExtPrice - inv.Discount) * (Decimal)
