decimal

问题 Comp sci professor gave us this problem in our homework... I'm not sure how to proceed and the code I have written seems to be failing miserably. Here is the prompt: (binary to decimal) Write a recursive method that parses a binary number as a string into a decimal integer. The method header is: public static String bin2Dec(String binaryString) write a test program that prompts the user to enter a binary string and displays its decimal equivalent. Any help greatly appreciated. Here is my code

问题 The following code currently outputs: 12.1 12.100 12.1000 12.00 12 12.0000 How can I change it so it outputs: 12.1 12.1 12.1 12 12 12 Math.Round seems to be the thing, but it makes me define how many decimal places I want, but I want them to be variable as above. If there is no mathematical way to do it, I'll just strip the zeros and decimal points off the right side of the strings, but would think there is a math way to handle this. using System; using System.Collections.Generic; namespace

问题 If I save C# decimal array to a binary blob with a binary writer, will I be able to seamlessly read this blob in Java or Python or R? Do these language have a corresponding data type or is there a cross-platform standard that .NET decimal adheres to? I am converting all my numeric data to decimals before storing, because when an array of decimals is diffed and then compressed, the resulting blob size is much smaller for real world data than a float blob compressed by any algo (my tests show c

问题 I have a question regarding the matcher. Currently I am trying to read a string and store all the digits into an array. My question is, how do you try to match both integers and decimals? I have an array of doubles called: double[] thisArray = new double[20]; Into this array, i am trying to store all the numbers I extract from the string. Matcher temp = Pattern.compile("(\d+)").matcher(x); That is my function for the matcher. But this only matches integers. I want to match both integers and

问题 This question already has answers here : Can someone explain this: 0.2 + 0.1 = 0.30000000000000004? [duplicate] (2 answers) Closed 5 years ago . I have written the following code for generating a range with floats: def drange(start, stop, step): result = [] value = start while value <= stop: result.append(value) value += step return result When calling this function with this statement: print drange(0.1,1.0,0.1) I expected to obtain this: [0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1.0] But

问题 I have a database table with these two columns: Amount: numeric (18,0) DecimalPlaces: numeric (18,0) This table can store amounts in various currencies, with the decimal place removed from the amount (I can't change this data model). For example, there might be two rows like this: 1290, 2 (This is £12.90, needs to appear as "12.90") 3400, 0 (This is 3400 Japanese Yen, needs to appear as "3400") I need an SQL query for both Oracle and SQL Server that will format each amount with the correct
