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 I use (hiding some internal implementation stuff): Int divide(Int numerator, Int denominator)const { if (denominator==0) return DIVIDE_BY_ZERO_ERROR; if (numerator==0) return 0; if (numerator.sign()!=denominator.sign())//result is negative return -((-numerator)/denominator); if (numerator==denominator) return 1; Int num=numerator.abs(); Int den=denominator.abs(); Int ret=0; while (num>den) { ret++; num-=den; } return ret; } Which is fairly slow, … |

Hi folks. I have a strange thing happening here. I have a loop where counter gets incrememnted by 0.1 starting from 0 and up to 1. In each iterration I use the counter in an expression with modulo operator. I get incorrect result when the counter has values of 0.8 and 1. This is the code: <?php echo '<pre>'; for($i = 0; $i <= 1; $i += 0.1) { // result of an expression $result = ($i * 10) % 10; // display $i, the expression and the result of the expression // when $i equals 0.8 and 1 the … |

Hello to everyone! This is my first post here, I hope you can help me. I'm making a class work in python and I'm a little lost: I have to use classes to represent monomials and polynomials, and the classes should contain methods to add, substract, multiply and divide them. So far, I've been able to create the whole monomials class, and almost all the polynomial class, but I can't find a way to code polynomial division. Surfing the web I've seen some methods based on binary conversion and things like that, but that doesn't seem to work for me … |

what I'm pretty sure I learned in school and what like every website said when I tried to look this up online was that the C++ code for generating a random number with floor: 1 and ceiling 100 (err I guess 101) is: [CODE]int number = rand() % 100 + 1; [/CODE] and that is generating a number... but everytime I compile the program, or run the same program more than once, 'number' always = 8... like everytime... and I tried changing it to [CODE]int number = rand() / 100 + 1; [/CODE] but then number always = 169.. not … |

I have created class menu and class number. I would like that my functions in class do sum, subtract, multiply, and divide. I've done sum, but I have problems with other functions. When I do difference, it is actually sum my numbers, and result of multiplication and division is 0 all the time. Could somebody help me with this problem. I have attached my implementation files and header files. |

I am trying to divide a integer (2's complement) by a power of 2 and then round that number toward zero. I am only allowed to use bitwise operators such as shifts, ~ ^ & | etc. I've came up with 2 expression but they dont seem to work. Can anyone help me out. x/(2^y) 1) x>>y example: 15/2^1=7 00001111(15) >>1 = 00000111 (7) Why doesn't this work? 2) a=~x b=a>>y c=~b example: 15/2^1=7 00001111(15), ~15 = 11110000, shift by y = 11111000, negate c = 00000111 = 7 Can someone explain why this doesnt work either? |

I am fairly new to programming but have been working on putting together a group of functions into one program. It is coming along nicely, but for some reason I can't get the loop on the divisibility function to work properly. When you prompt it to quit to return to the main menu, it interprets q as something you want to know divisibility for, not a prompt to quit. WHY????? [CODE]#include <iostream> #include <math.h> #include <iomanip> using namespace std; int divisCalc(); int calculator(); void enterPrompt(); int byteSize(); int main1() { do { cout << "\n\n~~\n~~\n~~\n~~ \n~~\n\nPress 1 for a calculator\n" … |

I am trying to edit my current homework assignment to include a loop that lets the user repeat the computation for new values until the user says they want to end the program.
