  • trunc

    AخA
     
    const x = Math.trunc(12.34 * 10);
    const y = Math.trunc(567.89 * 10);

  • round

     
    const x = Math.round(12.34 * 10);
    const y = Math.round(567.89 * 10);

  • floor

     
    const x = Math.floor(12.34 * 10);
    const y = Math.floor(567.89 * 10);

  • parseFloat to int

     
    const x = parseFloat((12.34 * 10).toFixed());
