Benchmark: IPv4 number to dotted decimal

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

let num = 3232235777;

Tests:

bitwise shift
const octet1 = (num >>> 24) & 255; const octet2 = (num >>> 16) & 255; const octet3 = (num >>> 8) & 255; const octet4 = num & 255; return `${octet1}.${octet2}.${octet3}.${octet4}`;
pow function
const octet1 = Math.floor(num / Math.pow(256, 3)); num = num % Math.pow(256, 3); const octet2 = Math.floor(num / Math.pow(256, 2)); num = num % Math.pow(256, 2); const octet3 = Math.floor(num / Math.pow(256, 1)); num = num % Math.pow(256, 1); const octet4 = num; return `${octet1}.${octet2}.${octet3}.${octet4}`;
Bitwise shift string concat
const octet1 = (num >>> 24) & 255; const octet2 = (num >>> 16) & 255; const octet3 = (num >>> 8) & 255; const octet4 = num & 255; return octet1 + '.' + octet2 + '.' + octet3 + '.' + octet4;
Bitwise shift string concat no variables
return ((num >>> 24) & 255).toString() + '.' + ((num >>> 16) & 255).toString() + '.' + ((num >>> 8) & 255).toString() + '.' + (num & 255).toString();
