JavaScript: Convert a value to a safe integer

JavaScript fundamental (ES6 Syntax): Exercise-29 with Solution

Convert Value to Safe Integer

Write a JavaScript program to convert a value to a safe integer.

• Use Math.max() and Math.min() to find the closest safe value.
• Use Math.round() to convert to an integer.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
// Define a function named to_Safe_Integer that converts a given number to a safe integer.
const to_Safe_Integer = num =>
 Math.round(Math.max(Math.min(num, Number.MAX_SAFE_INTEGER), Number.MIN_SAFE_INTEGER));

// Test the function with different input values.
console.log(to_Safe_Integer('5.2'));    // Output: 5
console.log(to_Safe_Integer('5.52'));   // Output: 6
console.log(to_Safe_Integer(Infinity)); // Output: 9007199254740991 (MAX_SAFE_INTEGER) 

Output:

5
6
9007199254740991
