3.14159.toFixed(2); // 3.14 returns a string
parseFloat(3.14159.toFixed(2)); // 3.14 returns a number
Math.round(3.14159) // 3
Math.round(3.5) // 4
Math.floor(3.8) // 3
Math.ceil(3.2) // 4js rounding
//There are meny ways of rounding...
Math.floor(5.5) //Answer 5, it alwas rounds down.
Math.round(5.5) //Answer 6, it simpily rounds to the closest whole number.

//You can do more things too...

// Retorna o valor 20
x = Math.round(20.49);
// Retorna o valor 21
x = Math.round(20.5);
// Retorna o valor -20
x = Math.round(-20.5);
// Retorna o valor -21
x = Math.round(-20.51);
// Retorna 1 (!)
// Note o erro de arredondamento por causa da inacurácia de aritmética de ponto flutuante
// Compare o exemplo abaixo com Math.round10(1.005, -2)
x = Math.round(1.005*100)/100;Copyright © 2021 Codeinu
