I need to add Column1 + Column2 And Display Result In Column3 But I need to do it for all rows in column3 automatically. I need a very short code. Thankyou.

Hello, I wrote a library for arbitrary precision arithmetic recently and spent a long time implementing efficient multiplication algorithms. Now I am looking to see if it is possible for me to optimize anywhere else. One place that I thought should be more optimizeable is my division algorithm. Right now …

Hello, I am working on an arbitrary precision arithmetic library. I already created a version that just stored numbers as "before decimal point [unsigned array]" and "after decimal point [unsigned array]". The issue is that it is both inefficient and incomplete. I would like to incorporate complex numbers into the …

Hi, I'm using this SQL statement to retrieve Value and Date which will then be plotted on a graph: SELECT DISTINCT assets.SEDOL,assets.Quantity,stock_names.value,stock_names.Fileid,date_header.dateid FROM assets,stock_names,date_header WHERE assets.Client_ref = '$clientref' AND stock_names.SEDOL = assets.SEDOL AND date_header.fileid = stock_names.fileid I'm also selecting Quantity. Instead of having to multiply out the arrays, how can …

I'm about at my wits' end trying to figure this out. This is homework, so any hints would be appreciated. I was tasked with filling in a few blocks of code (these are denoted by comment lines with a number resting in the middle) involving function calls in MIPS. The …

Hi guys. I am having issues with the output of this program. Can somebody tell me what I have to do to make this work correctly? Here is the code I have so far: import java.util.Scanner; //text scanner to parse primitive types and strings using regular expressions. public class Operations …

Hey there, I'm having issues with a custom string tokenizer I'm using for an assignment. I've looked around and haven't managed to find anything that really answers my question, so here goes nothing. Whenever I run the program and it runs the tokenizer, I get a seg fault. I'm fairly …

I am working to take c code from an academic paper and edit. I am studying cryptographic algorithms. I have ran the following code, but I am having a little difficulty understanding two things. First, the program uses unsigned long ints. When they are added or subtracted, I don't get …

From what I understand, ALU is exclusively for mathematical operations. For simple tasks like reading a web page, saving a text file, copying data etc., are arithmetic operations used or can the processor do it without using that? I don't have much knowledge about computer architecture, but it seems to …

So I'm trying to achieve this myself, but I decided to ask on this forum to see if anyone knew about some obscure project on sourceforge or something that did exactly this: I need to store very large numbers and perform arithmetic on them. I am storing the values in …

Hey, I have a set of types which are all arithmetic (have operators for addition, subtraction, multiplication, etc.). I want to aggregate any number of them into a single object, so I'm using the std::tuple class template and the <tuple> library (and Boost.Tuple for backward compatibility). My question is a …

I am having trouble with making my program read in binary and convert it into an integer so that I can do arithmetic on it, and then output it back out as binary. Here is my code. The first part of it works, and I can read in the 2 …

I have a program assignment in my C and Unix class that allows the user to enter two numbers in binary seperated by (*,+,-,or /). It then has to produce an answer and loop back to the beginning. It also has to have an option to exit. Can anyone help?

Dear All, I’m implementing a vector class that allows me to do vector arithmetic. What I’ve implemented is the following: [CODE]class mVec { private: float vec[3]; public: mVec(); mVec(const float * const parray); mVec(const float a, const float b, const float c); ~mVec(); mVec operator+(const mVec& param); mVec operator-(const mVec& …

Hey there, I'm having trouble creating a multiplication function for the program as I have two classes to keep in mind (Monomial and Polynomial). And if possible, a little advice on how to make my for statements in the arithmetic operators more flexible to user input such as i<PolynomialSize, which …

Hi guys!! I've to make a program that reads an arithmetical sentence from a textbox, e.g 12.3*34+4*5-3 and then on another textbox identify and display what is the content of the first textbox, for example taking the last ex: If I have this input: 12.3*34+4*5-3 The output should look like …
