问题 I am pulling SNMP information from an F5 LTM, and storing this information in a psql database. I need help converting the returned data in decimal format into ASCII characters. Here is an example of the information returned from the SNMP request: iso.3.6.1.4.1.3375.2.2.10.2.3.1.9.10.102.111.114.119.97.114.100.95.118.115 = Counter64: 0 In my script, I need to identify the different sections of this information: my ($prefix, $num, $char-len, $vs) = ($oid =~ /($vsTable)\.(\d+)\.(\d+)\.(.+)/);

问题 I have to create a java program that converts binary to decimal using the following steps. Being new at this I did something, but I don't know what I did wrong or how to continue. public class BinaryToDecimal { public static void main(String args[]){ long sum = 0; int result; String s = "1001010101011010111001011101010101010101"; for(int i = s.length()-1; i <= 0; i--){ result = (int)Math.pow(2, i); if(s.charAt(i) == '1') sum=sum + result; } System.out.println(sum); } } Use a loop to read

问题 So here is what I am trying to accomplish. I have coordinate data in two tables, which I am trying to link together with an Association table. It is a one to one association, so if I have 40 records in table A, 40 records in table B, then I should have 40 records in the association table. Now the data in these two tables is approximately the same, but never idential, in fact they rarely even have the same precision. One table(we'll say A) always has 6 decimal places, whereas table B may have

问题 I am quite new to regex and I have a problem with regex expression. I want to only allow a user to enter positive numbers, with or without one dot and up to 2 decimals (can be only 1 decimal also).

问题 I would like to make the decimals in the following string display as superscript: $string .= number_format(round($value, (int)$decimal_place), (int)$decimal_place, $decimal_point, $thousand_point); I'm not very smart but I have been trying since yesterday using different methods I've found searching stack overflow. Stuff like ."<sup> or just "<sup>" and also .'<sup>' and so many other combinations, but nothing works. I either get an error or the price disappears due to the error I introduce

问题 I have this code to add new column to datatable: DataColumn col = new DataColumn("column", typeof(decimal)); col.Caption = "Column"; mytable.Columns.Add(col); How can I specify decimal precision for this column so the value will always be in the format I want it to be? 回答1: You can not. However, you can format the value when you retrieve it from the table using String.Format function: String.Format("{0:0.##}", (Decimal) myTable.Rows[rowIndex].Columns[columnIndex]); 回答2: I had this same

问题 I'm working on getting an old piece of code working, from 2003. I'm trying to replicate an ATM style decimal textbox. This code claims to have worked for someone, but I am having trouble implementing it. Maybe someone has a better way of achieving this? Maybe in jQuery? 回答1: This is how I would solve it: http://jsfiddle.net/77bMx/86/ Handles numpad input as well as standard number keys Works with backspace Will revert to 0.00 if you somehow manage to produce illegal input (like backspacing

问题 When programming in C, say if I have integer h as a hexadecimal value and integer d as a decimal number. Can I do addition or subtraction between h and d? Or do they have have to be in the same number system? 回答1: Yes, you can write: int x = 100 - 0x100 + 0100; That mixes decimal with hex and octal. The values are all converted to binary anyway before the calculation occurs (and the compiler will do the calculation in this example; it won't be evaluated at runtime). And any of the constants
