A real world third party API takes a parameter of type fraction which is a struct of an int numerator and denominator. The value that I need to pass is known to me as a decimal string that is converted to a double. The range of possible values are, let’s say 10K to 300M but ..

** Write and debug a program for approximating the function f(x) on the interval [a, b] by a given method, m is the number of points at which the function is known (the size of the table). The function type is set to get the values of the table (xi, yi), i=1,2,…, m and check ..
I am trying to implement Fast Inverse Square Root for a fixed point number, but I’m not getting anywhere. I am trying to follow exactly the same principle as the article, except instead of writing the number in the floating point format x = (-1) ^ s * (1 + M) * 2 ^ (E-127), ..
The problem is that when multiplying a double type number like 9.58 and storing it in a integer type number, I get 957 instead of 958. When I separately try to assign 9.58*100 to an integer in a program, it works. How come? #include <bits/stdc++.h> using namespace std; double roundit(double x) { double e = ..
enter image description here PLease, forgive my ignorance but we didn’t really cover this in class and I’m really confused, and I have to finish this project. The image has some logic given by my professor about the step size adjustment. Source: Windows Que..
I’m porting a C++ approximation search algorithm to Python. The approximation search is designed to solve a localization in 2D space. For some reason, while my C++ code works great, my Python code produces incorrect results. For the example below (I’ve included both the C++ code, which will likely convey the algorithmic process better than ..
