(.0) float in Javascript
I am trying to do write a code for a function that displays a boolean after checking if the value is an integer or not. see my definition of an integer in my ideal outputs below when i call the…
Javascript – How MAX_SAFE_INTEGET 2 ** 53 – 1
We Know in Javascript it uses the STD IEEE 754 Double precision and we know that the Mantissa Section is 52 bit and there is implicit 1 bit but is not stored But if it isn't stored how it's actually…
Javascript – Double floating point operations using four IEEE rounding modes implemented in terms of round to nearest ties to even
I am looking to implement the RandomX Proof of Work hash function in JavaScript + WebAssembly. The README explains how this isn't possible: Web mining is infeasible due to the large memory requirement and the lack of directed rounding support…
Javascript – What is the best approach to deal with floating point issues when limiting the user input to 2 decimal places?
I am currently creating an application that allows users to input a weight and select their preferred unit, between kg and lbs. As of now, the database is written in Django and stores each user weight entry for a particular…
Javascript – How to handle division of a very small numerator?
I'm developing a JavaScript calculator and facing an issue with the division operation. When very small numerators are divided by large denominators, the result becomes "0". This isn't the desired behavior. Ideally, the calculator should either: Display a more informative…
Issue with System.Text.Json Serialization of Floating Point Numbers in C#
I'm encountering an issue with System.Text.Json in C# related to the serialization of floating-point numbers. When serializing a float with a decimal part (e.g., 4.0), the library seems to omit the decimal part, resulting in the JSON representation being just…
Visual Studio Code – Is it possible to use 80 bit floats with MSVC compiler?
I am using Visual Studio with the MSVC compiler. Basically any other compiler seems to support native 80 bit floats of x86/x64 CPUs, except MSVC. It seems that a workaround would be using inline assembler, but apparently MSVC does also…
PHP float precision and float-to-string/integer conversion
Observe the following case php -r 'echo 4.60*100, " ", (int)(4.60*100), PHP_EOL;' Surprisingly (to me) it prints this: 460 459 I understand that decimal 4.60 cannot be represented as finite binary number, but why string representation of float 4.60 prints…
Javascript – Without overflow and underflow, for a float number x, is x/4 always equals to x/2/2 (also for x*4 == x*2*2)?
For example, as I know, a float point x, which x/n^2 may not be equal to x/n/n, because in x/n/n, which would create an intermediate x/n first. For example: document.write(1.23456789/49 == 1.23456789/7/7); However, is x/4 == x/2/2 an exception, if…
Difference between JS and PHP decimal calculations
We do two types of decimal and numerical calculations with JS and PHP. And finally, we fix the decimal to the last two digits. For example: JS => var finalPrice = (float(num1) + float(num2)).toFixed(2); PHP => $finalPrice = number_format((float) (num1…
