numbers

So I have this list, we'll call it listA. I'm trying to get the [3] item in each list e.g. ['5.01','5.88','2.10','9.45','17.58','2.76'] in sorted order. So the end result would start the entire list over again with Santa at the top. Does that make any sense? [['John Doe', u'25.78', u'20.77', '5.01'], ['Jane Doe', u'21.08', u'15.20', '5.88'], ['James Bond', u'20.57', u'18.47', '2.10'], ['Michael Jordan', u'28.50', u'19.05', '9.45'], ['Santa', u'31.13', u'13.55', '17.58'], ['Easter Bunny', u'17.20', u'14.44', '2.76']] If you want to return the complete list in sorted order, this may work. This

View this code: function testprecision(){ var isNotNumber = parseFloat('1.3').toPrecision(6); alert(typeof isNotNumber); //=> string } I would have expected a number. If 'isNotNumber' should be a real number, recasting is the solution: alert(typeof parseFloat(isNotNumber)) //=> number [Edit] thanks for your answers. Precision is not so precise a term I conclude. It can represent the total number of digits of a number, or the number of fractional digits . Most people in the Netherlands (where I come from) think of precision in the 'number of fractional digits'-way. The javascript toPrecision

I encountered a weird behaviour in Perl. The following subtraction should yield zero as result (which it does in Python): print 7.6178E-01 - 0.76178 -1.11022302462516e-16 Why does it occur and how to avoid it? P.S. Effect appears on "v5.10.0 built for x86_64-linux-gnu-thread-multi" (Ubuntu 9.04) and "v5.8.9 built for darwin-2level" (Mac OS 10.6) It's not that scientific notation affects the precision so much as the limitations of floating point notation represented in binary. See the answers to the perlfaq4 . This is a problem for any language that relies on the underlying architecture for

I store some data in a database and I read those data with a cursor. All the data are 56.45 , 3.04, 0.03 type, so two numbers after the decimal point. Now I would like to sum them but it doesnt seem to be easy... I get those number with c.getDouble(3) then I add it to the sum variable like: sum+= c.getDouble(4) * multi multi is an integer between 1 and 100. Now my problem is that, after getting the sum variable I get a number like: 59.51999999999999999. I do not post a code, but there is no conversion except a string.valueOf for making the number appear on my widget. So anybody experienced

I hope you can help. I have a piece of code that is currently removing all the text from the cells in Column G. What I need is for this code to instead of removing the text I would like it to remove the numbers, and I only want it to remove the numbers at the beginning of the string/cell the rest of the data I would like to remain the same. I have attached a picture PIC.1 for betting understanding. PIC1 The code I currently have and I hope can be amended is below and as always any and all help is greatly appreciated . CODE Sub RemoveNonDigits() Dim X As Long, Z As Long, LastRow As Long,

Is there any regionalisation support built into XSL when it comes to formatting numbers? At present my underlying XML contains numbers in UK/US format, for example 54321.12345. I can do a select sum on this to give me a total in the same format. I can format the number using format-number(54321.12345, '###,###.#####') to give me 54,321.12345. However when I want this to run on a different region setting on my machine such as Central European countries which have the comma seperator as "." and the decimal seperator as "," I want to format my numbers in this way to give me 54.321,12345. Is there

Is there a c++ structure or template (in any library) that allows me to do conversion between decimal and any other base (much like what bitset can do) ? Yes, you can use unsigned int : unsigned int n = 16; // decimal input unsigned int m = 0xFF; // hexadecimal input std::cout << std::dec << "Decimal: " << n << ", " << m << std::endl; std::cout << std::hex << "Hexadecimal: 0x" << n << ", 0x" << m << std::endl; Octal is also supported, though for other bases you had best write your own algorithm - it's essentially a three-liner in C++: std::string to_base(unsigned int n, unsigned int base) {

I am using Adempiere which has database Oracle I have window called Stock Code from table called M_StockCode The fields are Code and Description . Currently, Code data type is Number and Description is Varchar2 I want to input Sparepart with Code 01 , and Body Repair with Code 02 . As I input the data in Adempiere and save it, what will show is Sparepart with Code 1 (without leading zero) I've tried putting LPAD function but it's still failed. How can I put 01 both in Adempiere interface and in database? Any suggestion will be appreciated :) A NUMBER cannot have leading zero, a STRING can. If

I'm trying to get a string with multiple numbers to a single int like this: x="5+5" --amount of numbers is not constant y=tonumber(x) print(y) The result of this is nil while it should be 10 (int). The only way I could solve this is by first searching all the "+" and "-" with string.find() then cutting it to all the necessary parts and from there just tonumber() . It feels stupid to code at least a hundred rows of code for such a simple problem. tonumber can be used only on a string that is a real number, not an arithmetic expression. You can load the string and run it: x = "5 + 5" func =
