And how about testing the value parameter to see if it is null / empty:

function writeTotal(value) {

var innerHtml = "";

if (value === window.undefined || value === null || value === "") {
    innerHtml = "R$ 0,00";
}
else {
    innerHtml = floatToMoneyText(value);
}

$('#total').html(innerHtml);
};

A reduced form:

function writeTotal(value) {
    $('#total').html(floatToMoneyText(value));
}

This floatToMoneyText could probably also be converted to jQuery, but would have to know what you do exactly in it
