Script Preparation code:
var numbers = []; for(let i = 0; i < 100000;i++) { numbers.push(Math.random()*100000); numbers.push(Math.floor(Math.random()*100000)); } numbers.sort( (a,b) => (0.5)-Math.random());
Tests:
Modulus 1
let integerCount = 0; for(let i = 0; i < numbers.length;i++) { if(!(numbers[i]%1)) { integerCount+=1; } }
Number.isInteger
let integerCount = 0; for(let i = 0; i < numbers.length;i++) { if(Number.isInteger(numbers[i])) { integerCount+=1; } }
