海外TECH	DEV Community	Dealing with Floating Point Numbers in JavaScript: Lessons Learned	https://dev.to/kyosifov/dealing-with-floating-point-numbers-in-javascript-lessons-learned-2070	Dealing with Floating Point Numbers in JavaScript Lessons Learned Dealing with Floating Point Numbers in JavaScript Lessons LearnedAs a developer working on an BB E Commerce system I recently encountered an issue related to decimal precision that taught me a valuable lesson about handling money value in JavaScript The problemA user had reported that when attempting to refund an order with a specific amount the amount entered was off by one cent After investigating the issue I discovered that it was caused by how JavaScript handles floating point numbers The IEEE standard is used by JavaScript to represent and manipulate floating point numbers It provides a way to represent a wide range of values including very large and very small numbers but it can also lead to rounding errors when working with certain decimal values The number was one of those floating point numbers that had this issue there are numerous more see title Since cents are used in the backend and database and not decimals conversion from decimal to cents integer was required For an example in the BE the value is represented as and in the FE is used for input elements and certain display features In this case the refund amount was multiplied by to convert it to cents the rounding issues caused the return value to be instead of the expected Simple solutionTo solve this issue there were options available I could have used toFixed Or round Math round Or rely on a library like decimal js or big jsI decided to go with the second approach as the return value had to be a number still The first approach required to parse it from string to integer again and the third approach was a big step for a small problem Most of the mainstream languages use the same standard as JavaScript so it s a condition on them as well Here is an example in C include lt stdio h gt include lt stdlib h gt int main int val printf d val return Avoiding the issue getting to productionThere were unit tests to verify the logic however it did cover only the happy paths or values with one invalid value being tested While it was an OK test coverage it was not enough to reveal the floating point problem So property testing Property testing is a testing method that generates random inputs to test if a program behaves correctly for a range of inputs By using property testing in addition to unit tests we can ensure that our code is robust and handles edge cases appropriately In the case of the decimal precision issue had we used property testing we might have discovered the issue earlier Here is an example I am using Vitest as a testing library and Fast Check for property testing essentially we are using fc from fast check but we haveimport test fc from fast check vitest import it describe expect from vitest function toCents value number return Math round value describe Money value gt test fc float min max noNaN true is converted correctly to cents floatValue gt const value parseFloat floatValue toFixed using another approach in the test to get the correct value so that we can confirm that toCents works correctly const expectedValue parseInt value toFixed expect expectedValue toEqual toCents value ConclusionThe lesson to be learned from this experience is that when working with money in JavaScript it s important to be aware of the limitations of the IEEE standard and try to prevent similar issue from occurring in the future I hope that the post has been helpful and has given some insights on working with floating point numbers	2023-03-17 11:09:33
