    Вроде так: строку
    Code:
    document.getElementById('fieldRes').innerHTML=pars  eInt(document.getElementById('field1').value) / parseInt(document.getElementById('field2').value) /24;
    замнить на :
    Code:
    document.getElementById('fieldRes').innerHTML=(parseInt(document.getElementById('field1').value) / parseInt(document.getElementById('field2').value) /24).toFixed(2);
