toFixed
let numero = 123.45678; let resultado = numero.toFixed(2); // "123.46" como string resultado = Number(resultado); // Converte de volta para número, se necessário
Round
let numero = 123.45678; let resultado = Math.round(numero * 100) / 100; // 123.46
floor
let numero = 123.45678; let resultado = Math.floor(numero * 100) / 100; // 123.45
Bitwise
let numero = 123.45678; let resultado = (numero * 100 | 0) / 100; // 123.45
Math.trunc
let numero = 123.45678; let resultado = Math.trunc(numero * 100) / 100; // 123.45
