JavaScript: Check if two given numbers are approximately equal to each other

JavaScript fundamental (ES6 Syntax): Exercise-256 with Solution

Write a JavaScript program to check if two given numbers are approximately equal to each other.

• Use Math.abs() to compare the absolute difference of the two values to epsilon.
• Omit the third argument, epsilon, to use a default value of 0.001.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
const approximatelyEqual = (v1, v2, epsilon = 0.001) => Math.abs(v1 - v2) < epsilon;
console.log(approximatelyEqual(Math.PI / 2.0, 1.5708));

Sample Output:

133
100
