I have code like: lblFranshizShowInvwNoskhehEdit.Text = string.Format("{0:n}", (double)(int.Parse(drDarman["FranshizDarsad"].ToString()) * Convert.ToInt64(RadNumerictxtPayInvwNoskhehEdit.Text)) / 100); But {0:n0} string format forces the label's text to not have decimal digits and {0:n} string format forces the label's text to have 2 decimal digits (default). In my scenario I just want decimal digits when necessary / without rounding them / how can I do that? You can just do: string.Format("{0}", yourDouble); It will include only digits when necessary. If you want other examples of formatting

I asked a question earlier that involved pulling large primes from a text file and putting them into another file. It was supposed to grab every prime up to and including the first prime after 2^32, and for some reason this script stopped working. #!/bin/bash n=4294967296 last=0 while read number do if [ $last -gt $n ] then break fi echo $number last=$number done < primes.txt > primes2.txt It ended up looping through these 11 numbers: 4232004449 4232004479 4232004493 4232004509 4232004527 4232004533 4232004559 4232004589 4232004593 4232004613 004437 The original file didn't have 004437 in it,

BETWEEN is used in a WHERE clause to select a range of data between two values. If I am correct whether the range's endpoint are excluded or not is DBMS specific. What I can not understand in the following: If I have a table of values and I do the following query: SELECT food_name FROM health_foods WHERE calories BETWEEN 33 AND 135;` The query returns as results rows including calories =33 and calories =135 (i.e. range endpoints are included ). But if I do: SELECT food_name FROM health_foods WHERE food_name BETWEEN 'G' AND 'O'; I do not get rows with food_name starting with O . I.e. the end of

While trying to compute the width of an hidden element I found that jquery.width() returns 0 for that elements' width. I found out that using jquery.css('width') would return the correct width by using the declared style width (even if that value is different from the initial stylesheet). The problem is that the css('width') method returns a string, generally in a "100px" fashion. My question resolves into: how to retrieve the number from the "100px" string? Is there an easy way? Fenton If it always returns in px format, "100px", "50px" etc (i.e. not "em" or percent), you could just... var

How do I check if a string in a MySQL field contains a number then delete them? Example table: tbl_tags ------------- | id | tag | ------------- | 1 | hello | | 2 | hello2 | | 3 | 2hello | | 4 | hel3lo | ------------- The only way I can think of is to do each number individually and use LIKE '%1%' OR LIKE '%2%' etc. But there must be an easier way? Check out the MySQL Regex methods . Something like the following should work. SELECT * FROM table WHERE tag REGEXP '[0-9]' user3200518 SELECT * FROM clients WHERE name REGEXP '^[[:digit:]]+$' ORDER BY `clients`.`country_id` DESC LIMIT 0 , 30 this is

Say I have a multi-digit integer in C. I want to break it up into single-digit integers. 123 would turn into 1 , 2 , and 3 . How can I do this, especially if I don't know how many digits the integer has? int value = 123; while (value > 0) { int digit = value % 10; // do something with digit value /= 10; } First, count the digits: unsigned int count(unsigned int i) { unsigned int ret=1; while (i/=10) ret++; return ret; } Then, you can store them in an array: unsigned int num=123; //for example unsigned int dig=count(num); char arr[dig]; while (dig--) { arr[dig]=num%10; num/=10; } As a hint,

I was working on Project Euler 40 , and was a bit bothered that there was no int.Parse(char) . Not a big deal, but I did some asking around and someone suggested char.GetNumericValue . GetNumericValue seems like a very odd method to me: Takes in a char as a parameter and returns...a double? Returns -1.0 if the char is not '0' through '9' So what's the reasoning behind this method, and what purpose does returning a double serve? I even fired up Reflector and looked at InternalGetNumericValue, but it's just like watching Lost: every answer just leads to another question. Remember that it's

In C language Octal number can be written by placing 00 before number e.g. Editor's note: it is a single leading 0 that identifies a number literal as an octal value in C; additional 0 instances have no effect. int i=0012; //equals 10 in decimal I found the equivalent of Hexadecimal in C# by placing 0x before number e.g. int i=0xA; //equals 10 in decimal Now my question is: Is there any equivalent of Octal Number in C# like in C to represent any number as Octal? No, there are no octal number literals in C#. For strings: Convert.ToInt32("12", 8) returns 10 . No there isn't, the language
