Questions tagged [integer-division]

Anything related to the integer division operation, i.e. that special form of division which is performed between two integer numbers and which in math results in a quotient and a remainder. This is mostly relevant for languages which have specific integer data-types, for which the division is an integer division, or for languages having a specific operator/function to perform integer division.

Divisor value in for loop is mysteriously (?) changing

So I have been at this for hours, and I'm honestly completely stuck. I've wrote a for loop that counts the amount of numbers in an integer, but I've found that the divisor value changes once i enter a number above 10 digits, and I can't figure out…

Division of integers result in integer not in float? (Raptor Flowchart)

I want to draw a flowchart in Raptor, which will do division of integers and will give result in integers not in floating point numbers like: 2/5=2.5 but I want the result to be 2 which is the quotient part.

Is Math.floor(x/y) deterministic?

According to this post, floating point numbers in JavaScript are not deterministic. I wonder, is the following code deterministic? z = Math.floor(x/y) If not, how can I do deterministic integer division in JavaScript? Edit: I would like to know if…

The remainder in integer division is negative in Python

Please explain why: print ((- 1) % (-109)) # prints -1 print (1 % (-109)) # prints -108 Why is the result negative if the terms of the wording of the remainder 0 <= r < b

In order to access first Digit of an integer dynamically, is using a String or Division more efficient?

There's two methods I've read about, divide by 10 repeatedly (or slightly more efficiently, divide in a way to minimize division operations) i.e. int getFirstDigit(unsigned int num) { if (num >= 100000000) num /= 100000000; if (num…

Why do I have to add a decimal to get this math correct in C++

I was calculating the volume of a sphere and after tons of research I found that I cannot use: float sphereRadius = 2.33; float volSphere = 0; volSphere = (4/3) * (M_PI) * std::pow(sphereRadius, 3); But must add the 3.0 instead to get the right…

Incorrect result of dividing the product of two integers by their gcd

We know that for two numbers 'a' and 'b'; product of a & b is equal to the product of GCD(a,b) and LCM (a,b). So in order to find the LCM of two numbers I wrote this algorithm in Python: def gcd(a,b): if b==0: return a else: a_rem =…

How to find the value of integer k efficiently for which q divides b ^ k finitely?

We have given two integers b and q, and we want to find the minimum value of an integer 'k' for which q completely divides b^k or k does not exist. Can we find out the value of k efficiently? Not just iterating each value of k (0, 1, 2, 3, ...) and…
