numbers

问题 Let us suppose we have a number circle, that ranges from -180 to 180, looking something like this: 180/-180 *** *** *** 90 *** *** -90 *** *** *** 0 A section of the circle is always swept in a clockwise direction. How can you tell if a number is inside or outside of the interval swept? In the following sample I/O, the first two numbers represent the interval and the third number is the number being checked. Output is true if the point is (inclusively) inside the interval, false otherwise. 2

问题 I'm trying to get NSDecimalNumber to print out large numbers, 15 or more digits. At 15 digits I see 111,111,111,111,111. Above 15 digits I see 1,111,111,111,111,110 even though the number being formatted is 1111111111111111. An example to illustrate my problem: NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init]; [formatter setNumberStyle:NSNumberFormatterDecimalStyle]; [formatter setMaximumSignificantDigits:25]; [formatter setUsesSignificantDigits:true]; NSDecimalNumber* test =

问题 hi as suggested in previous question, i will try more clarify what i want to achieve. as in file1, in column $4 i have numbers which are not continuosly sequenced like 1,2,3,4,5.. , it means i need print those missing ones e.g. after number 3 i should get number 4 and so on cat file1 A R5 A48 1 B R5 A48 2 C R4 A48 3 D R8 A48 15 E R9 A48 22 F R20 B55 21 G R55 B22 19 R B1 I77 14 AA B8 PP 18 BX A255 PA 7 CA A77 PB 10 WW W7 PX 11 i find out partly solution in this awk one liner returning arr=($

问题 I am trying to find all floating number (could be in exponential forms with -/+ prefix or not). For example, the following is the valid format: -1.2 +1.2 .2 -3 3E4 -3e5 e-5 The source of text contains several numbers separated with space or comma. I need to use regular expression to tell tell if there is any invalid number (e.g. 1.2 3.2 s3) s3 is not a valid one list every single valid number I have no idea how to get (1) done but for (2), I am using boost::regex and the following code

问题 I have this script that was maked by another memeber of stackoverflow but I need to put a comma separator for thousands numbers. How I can do that? (function($) { $.fn.currencyInput = function() { this.each(function() { var wrapper = $("<div class='currency-input' />"); $(this).wrap(wrapper); $(this).before("<span class='currency-symbol'>$</span>"); $(this).change(function() { var min = parseFloat($(this).attr("min")); var max = parseFloat($(this).attr("max")); var value = this.valueAsNumber;

问题 used the following stored procedure to find reverse of a number , but it is showing error:use the right syntax to use near loop. DELIMITER // CREATE PROCEDURE ggrepeat1() begin declare num1 int; declare num2 int; declare rev int default 0; set @num1:='&num1'; while num1>0 loop set @num2:=num1 mod 10; set @rev:=num2+(rev*10); set @num1:=floor(num1/10); end loop; dbms_output.put_line('Reverse number is: '||rev); end// DELIMITER ; 回答1: The while loop in mysql should be used in this like. This is

问题 i am trying to write a function that when given a list would return a lsit in random order. this is how i thought of doing it(the list is of length 52): generate random number between 1 and 52 take that element of the list. a = [1,2,3..] !! getRandom 52 then recursively call same function.. generate random number between 1 and 51 and call on list with first element we picked removed. (delete a [1,2,3..]) !! getRandom 51 And so on..after puting all elements picked in a list we get same list
