How to convert array of decimal strings to array of integer strings without decimal in JavaScript
We are required to write a JavaScript function that takes in an array of decimal strings. The function should return an array of strings of integers obtained by flooring the original corresponding decimal values of the array.
For example, If the input array is −
const input = ["1.00","-2.5","5.33333","8.984563"];
Then the output should be −
const output = ["1","-2","5","8"];
Example
The code for this will be −
const input = ["1.00","-2.5","5.33333","8.984563"];
const roundIntegers = arr => {
const res = [];
arr.forEach((el, ind) => {
const strNum = String(el);
res[ind] = parseInt(strNum);
});
return res;
};
console.log(roundIntegers(input));Output
The output in the console −
[ 1, -2, 5, 8 ]
