问题 Following the previous answers How to make a condition based on the number of decimals a number has with the IFS and AND functions in Google Sheets? The formula given didn't return a result for whole numbers (any number without decimals, for example: 1(.00), 12(.00) etc.). To make it return a result also for inputs with whole numbers, I thought of some formula like this: =IF(A1=(a whole number/number without decimals),A1.00(A1 formatted as a whole number with two decimals),A1(A1 with any

问题 I'm a newbie to JS and it would be extremely useful to know what the differenece is between the following two if statement conditions... First condition (not actually working): if ( window.location.pathname == '/#register' ) { // Code } Second condition: if (document.URL.indexOf("#register") >= 0) { // Code... } FYI, this would help me solve a bug I'm experiencing here 回答1: The first checks for an exact match. And it does it on the pathname, which doesn't include the hash, so it probably

问题 I am a novice at C#, yet I know I should be able to figure this out. My searching skills have not given me a direct answer either. I have two application settings that are stored in string arrays (they have been split from a , separated list). Ultimately I want to run one chunk of code, conditional upon both settings. Conditions are: If settings exist in array 1 (domattributes), run the code on each setting value. If settings also exist in array 2 (intlattributes), run the code on each

问题 I'm trying to create an IF Statement on Sheets so that if at least one of the last 3 columns (W,X,Y) contains 'YES' then column Z will say 1. If all of them are empty or contain 'NO' then column Z will say 'FALSE' or 'NO'. Please see what I have below, each time I do it, it only takes the data from W and ignores X and Y. =IF(W3='DATA VALIDATION'!B2, 1, AND(X3='DATA VALIDATION'!B2,1,AND(Y3='DATA VALIDATION'!B2,1,)) ) 回答1: Use a countif across W:Y to see if there is a Yes . Any result greater

问题 I am attempting to trace the execution of a piece of code that contains a for loop with two if conditionals . But I need help understanding exactly how for loops are executed in python. Please consider the following example: numAs = 0 numEs = 0 aStr1 = 'abcdefge' def someFunc(aString): 1. for i in range(len(aString)): 2. if s[i] == 'a': 3. numAs += 1 4. continue 5. if s[i] == 'e': 6. numEs += 1 7. if numEs > numAs: 8. break 9. print(someFunc(aStr1)) Question: Using aStr as a parameter how

问题 Hello I am attempting to do this with mySQL. I tried using SELECT IF and CASE to alter titles. Every title description has "A " in front of the description; even if the second word starts with a consonant. So I'm trying to query the descriptions but edit the ones with a leading consonant to start with "An ". CASE WHEN description LIKE ('A A%') THEN CONCAT('An ', TRIM(LEADING 'A ' FROM description)) WHEN description LIKE ('A E%') THEN CONCAT('An ', TRIM(LEADING 'A ' FROM description)) WHEN

问题 I'm new to Ruby. Is there a way to do the following? hash = { :key1 => defined? value1 ? value1 : nil, :key2 => defined? value2 ? value2 : nil } puts hash[:key1] # outputs: ["expression"] The above code stores the expression, instead of the value (if it is defined) or nil (if it is not defined). 回答1: You're looking for lambda , or Proc . hash = { :key1 => lambda { defined?(value1) ? value1 : nil }, :key2 => lambda { defined?(value2) ? value1 : nil } } hash[:key1].call http://www.ruby-doc.org

问题 I have a nested if statement is returning "False" rather than the expected outcome. Scenario Table "High VoltageCables" has data in it that default to numeric but may contain characters: kVa Table "Master" checks "High VoltageCables" data as blank or not blank, and returns "Failed Check 1","Passed Check 1". This works fine. Table "Meta" then checks the results of "Master" and then tests "High VoltageCables" data for length between 1 and 6, regardless of whether record is numeric or string.

问题 I am using Notepad++ to create a simple web page where a user types in two numbers into a text box, and then presses a button.
