问题 Have decimal amount, want to trim to 2 decimal places if present 回答1: Have you tried using value = Decimal.Round(value, 2) ? For example: using System; class Test { static void Main() { decimal d = 1234.5678m; Console.WriteLine("Before: {0}", d); // Prints 1234.5678 d = decimal.Round(d, 2); Console.WriteLine("After: {0}", d); // Prints 1234.57 } } Note that this is rounding rather than just trimming (so here it's rounded up)... what exactly do you need? Chances that the Decimal struct

问题 This is a follow up to another post i made about inserting an integer into mongodb. I have this working just fine by using the (int) but now when it inserts the number into the db is strips everything after the decimal. So if i had 154.65 it would be inserted into the mongodb as 154 with nothing after the decimal. My question is how do i get this to keep all numbers after the decimal? Also if anyone has a link to these sting/numeric functions i'd appreciate a reference. Thanks. $number["xyz"]

问题 I do my php work on my dev box at home, where I've got a rudimentary LAMP setup. When I look at my website on my home box, any numbers I echo are automatically truncated to the least required precision. Eg 2 is echoed as 2, 2.2000 is echoed as 2.2. On the production box, all the numbers are echoed with at least one unnecessary zero, eg 100 becomes 100.0. On both boxes, the PHP version is 5.2.5. Does anyone know offhand if there is a setting I can change which will force PHP to automatically

问题 The Stack Exchange Data Explorer allows SQL queries against a Stack Exchange database.

问题 I have a pointer address I obtained from the extern char etext , end and edata . I also obtained address of variables using &<Variable Name> . Both are hexadecimal pointer addresses. I need to do arithmetic on those addresses in decimal. How do I do so? I need to convert the address into an int in decimal so I can find size of memory segments by subtracting addresses. 回答1: Math is math. It doesn't matter what base you do it on. The computer is working only in base 2 anyway. Only during input

问题 How would I go about converting a measurement from, for example, 12.5 feet to 12ft 6in? How would I created that second number which reads only the decimal place when multiplying by 12? right now I have double Measurement01 using other variables and some math to get me the feet in decimals. I send that to a textview with farf.setText(Measurement01 + " " + "ft"); Any help would be appreciated! 回答1: Substract the integer portion: float measurement = 12.5; int feet = (int)measurement; float
