2. c++ - Dividing 1 by any number gives 0 - Stack Overflow

   stackoverflow.com/questions/13163964

   When I try to divide 1/60 or 1/(60*60) it gives 0. Even in debugger window. Even in debugger window. I am a bit confused what it could be, because 2/3 or 2.5/6 give results.

3. Which is better option to use for dividing an integer number by...

   stackoverflow.com/questions/10681375

   A few months ago I worked on a bitmap convolution routine which involved stepping through an array of integers and dividing each element by 2. I did all kinds of things to optimize it including the old trick of substituting "x>>1" for "x/2". When I actually timed both ways I discovered to my surprise that x/2 was faster than x>>1

4. Newton’s interpolating polynomial [python] - Stack Overflow

   stackoverflow.com/questions/14823891

   If you don't want to use any function definition, then here is the simple code: ## Newton Divided Difference Polynomial Interpolation Method import numpy as np x=np.array([0,1,2,5.5,11,13,16,18],float) y=np.array([0.5, 3.134, 5.9, 9.9, 10.2, 9.35, 7.2, 6.2],float) n=len(x) p=np.zeros([n,n+1])#creating a Tree table (n x n+1 array) value =float(input("Enter the point at which you want to ...

5. java - How do I divide so I get a decimal value? - Stack Overflow

   stackoverflow.com/questions/665018

   I want to know how to get remainder and quotient in single value in Java. Example: 3/2 I should get value as 1.5. If I use the / operator I get only the quotient. If I user the % operator I...

6. Integer division in Python 2 and Python 3 - Stack Overflow

   stackoverflow.com/questions/21316968

   Well, it is somehow subjective, but for me, coming from other languages, it was confusing that dividing 3/2==1. Many people may agree, because float division is the default in python 3 – bgusach

7. math - Why is 0 divided by 0 an error? - Stack Overflow

   stackoverflow.com/questions/3236489/why-is-0-divided-by-0-an-error?noredirect=1

   So in this case, 0/0 = 2 (didn't I tell you it was a strange beast?) Here's another bit of weirdness with 0. Let's say that 0/0 followed that old algebraic rule that anything divided by itself is 1. Then you can do the following proof: We're given that: 0/0 = 1 Now multiply both sides by any number n. n * (0/0) = n * 1 Simplify both sides:

8. Can someone explain this: 0.2 + 0.1 = 0.30000000000000004?

   stackoverflow.com/questions/7545015

   Neither 0.1 nor 0.2 are exactly representable in binary floating point. And nor is 0.3. A number is exactly representable if it is of the form a/b where a and b are an integers and b is a power of 2.

9. python - Make division by zero equal to zero - Stack Overflow

   stackoverflow.com/questions/27317517

   If you don't mind rolling up the sleeves to get a little bit more performance, here is a C++ version: static inline double div_positive_or_0(double a, double b) noexcept { // Convert the quotient of division by non-positive numbers to 0.

10. What's the underlying implimentation of integer division in...

    stackoverflow.com/questions/60253815

    However 1 / 0.2 returns 5, and math.floor(1 / 2) also returns 5. It's giving a number one less than what integer division should. It's giving a number one less than what integer division should. The // operator returns a 5 if you divide 10 by 2, but 1 divided 0.2 does not work correctly.

11. floating point - Why 0.1 + 0.1 == 0.2? - Stack Overflow

    stackoverflow.com/questions/47485048

    If we were using decimal with 5 significant digits, you might be surprised that 1 / 3 * 3 == 1 does not hold (1 / 3 would compute as 0.33333 and that times 3 would compute as 0.99999, which is different from 1), whereas 1 / 4 * 4 == 1 does hold (1 / 4 would compute as 0.25, and that times 4 would compute as 1).
