问题 i'm automating excel, using the macro system as a guide to what i should do through automation. When i format a column as a date, the macro generated a NumberFormat for the column to be: [$-409]m/d/yy h:mm AM/PM;@ i'm trying to decipher what this really means. i gather from googling, that the values in the square brackets are a "condition" , and that if the condition: $-409 is met, then it will use the NumberFormat m/d/yy h:mm AM/PM if not, it uses the NumberFormat @ The references i find say

问题 How to format numbers like SO with C#? 10, 5k, ... 回答1: Like this: ( EDIT : Tested) static string FormatNumber(int num) { if (num >= 100000) return FormatNumber(num / 1000) + "K"; if (num >= 10000) { return (num / 1000D).ToString("0.#") + "K"; } return num.ToString("#,0"); } Examples: 1 => 1 23 => 23 136 => 136 6968 => 6,968 23067 => 23.1K 133031 => 133K Note that this will give strange values for numbers >= 10 8 .

问题 How could I convert from float to string or string to float? In my case I need to make the assertion between 2 values string (value that I have got from table) and float value that I have calculated. String valueFromTable = "25"; Float valueCalculated =25.0; I tried from float to string: String sSelectivityRate = String.valueOf(valueCalculated ); but the assertion fails 回答1: Using Java’s Float class. float f = Float.parseFloat("25"); String s = Float.toString(25.0f); To compare it's always

问题 I have 2,299.00 as a string and I am trying to parse it to a number. I tried using parseFloat , which results in 2. I guess the comma is the problem, but how would I solve this issue the right way? Just remove the comma? var x = parseFloat("2,299.00") alert(x); 回答1: Yes remove the commas: parseFloat(yournumber.replace(/,/g, '')); 回答2: Removing commas is potentially dangerous because, as others have mentioned in the comments, many locales use a comma to mean something different (like a decimal

I tried this following code to generate reg no. for(int i=0000001;i<3;i++){ System.out.println("ABC"+i); } But I got output as ABC1 ABC2 ABC3. This is not needed. Please advice. 回答1: Numbers do not have significant leading zeros. (Never mind that the code actually uses an octal number literal in Java.) See

问题 I'm looking for a decimal to alphanumeric number base converter library in Visual Basic that does not use recursion. I found: http://visualstudiomagazine.com/articles/2010/07/20/when-hexadecimal-is-not-enough.aspx which includes a demo app but discovered that it uses recursion. The problem with it using recursion became apparent when I attempted to integrate the library into my own Visual Studio Express 2010 Visual Basic project: I got a stack overflow exception. Now I could consider

问题 I'm trying to set a number format (South African Rand currency, no decimals) to a range like so: range.NumberFormat = "_ R * # ##0_;"; where range is of type Microsoft.Office.Interop.Excel.Range however when I open the spreadsheet and check the formatting string by choosing custom format the string now looks like this: _ \R * #\ ##0_; and these added slashes means that only the first thousand separator (a space) is present and the rest are left off. I've also tried this: range.NumberFormat =
