When I run fma-optimized horner-scheme polynomial computation (for cosine approximation), it makes 0.161 ulps error on FX8150 but 0.154 ulps on godbolt.org serv
Could you please explain this code: printf("Value1: %0.1f \n", (float)124/100); // = 1.2 printf("Value1: %0.1f \n", (float)125/100); // = 1.2 printf("Valu
I am working on a simple C++ code generator created by excel parsing and I will need to distinguish between number type. I can deduce integer size (e.g. uint_32
I am preparing a code to create an array of 10^5 rows and 10^4 columns with Python. Each element of the array is a float (1.504096744947185, e.g.), which takes
For the below calculation, the expected result is -0.0000671. But the result of the code is -0.00006800000. declare @V_A decimal (38,11) = 99.99329,
I understand that if 1 is added to INT_MAX it will overflow and we will get the negative maximum. It is connected in a cycle. In the code below can I calculate
I am using "(float)$val" for some calculation, but for some decimal value like -0.00000025478625 (float)-0.00000025478625 is resulting to -2.5
Precision gets lost for big number. I am using tail input plugin to read file and data inside a file is in json format. Below is the configuration [inputs.tail]
An algorithm I'm using needs to squeeze as many levels of precision as possible from a float number in Javascript. I don't mind whether the precision comes from
Why the precision of the float is up to 6 digits after the decimal point and the precision of the double is up to 15 digits after the decimal point? Can anyone
C++ has std::nextafter(), which returns the next representable value after a given floating-point value f. In my case, I'd like to allow for n bits of slop in t
I was comparing the result of my following python calculation with Mathematica: https://www.wolframalpha.com/input?i=sum+%28500+choose+r+%29%28-1%29%5Er+%2F%28r
For the following code: https://godbolt.org/z/WcGf9hEs3 #include <stdio.h> int main() { char temp_buffer[8]; double val = 25.3; sprint
I am trying to use XGBoost for classification. I am pretty doubtful on its accuracy. I have applied it with default parameters and the precision is 100%. xg_c
I'm writing a teaching document that uses lots of examples of Python code and includes the resulting numeric output. I'm working from inside IPython and a lot
I'm having some trouble with the test cases for Project Euler #1 on HackerRank and was hoping someone with some JS experience on HackerRank could help out. B
In the CUDA Programming guide, v11.7, section B.24.6. Element Types & Matrix Sizes, there's a table of supported type combinations, in which the multiplicat

Given a double, I want to round it to a given number of points of precision after the decimal point, similar to PHP's round() function. The closest thing I can
What is the difference between double-precision data type and numeric data type in R programming?
