HTML Preparation code:
<div id="result">
Script Preparation code:
const result = document.getElementById("result"); const b1 = ((2n ** 63n) - 1n) / 5n; const b2 = 5n; let b3 = 0n; const n1 = Number.MAX_SAFE_INTEGER / 5; const n2 = 5; let n3 = 0;
Tests:
Bigint
b3 = b1 * b2; b3 = b3 - b2; b3 = b3 / b2; b3 = b3 + b2; b3 = b3 % b2;
Number
n3 = n1 * n2; n3 = n3 - n1; n3 = n3 / n2; n3 = n3 + n2; n3 = n3 % n2;
BigInt and textContext
b3 = b1 * b2; b3 = b3 - b2; b3 = b3 / b2; b3 = b3 + b2; b3 = b3 % b2; result.textContent = b3;
Number with textContext
n3 = n1 * n2; n3 = n3 - n1; n3 = n3 / n2; n3 = n3 + n2; n3 = n3 % n2; result.textContent = n3;
