HTML Preparation code:
<!--your preparation HTML code goes here-->
Script Preparation code:
const numbers = (new Array(5000)).map(() => Math.random() * 10000);
Tests:
Floor
let truncated; while(true){ const number = numbers.pop() if(number === undefined) break; truncated = Math.floor(number); }
Bitwise
let truncated; while(true){ const number = numbers.pop() if(number === undefined) break; truncated = number | 0; }
Bitwise NOT
let truncated; while(true){ const number = numbers.pop() if(number === undefined) break; truncated = ~~number; }
Parse
let truncated; while(true){ const number = numbers.pop() if(number === undefined) break; truncated = parseInt(number); }
