Yes, Julien, but from the context of his code:
document.getElementById("beginning_funds").innerHTML = standard_premium*excessPremium_Percent;
It was pretty clear that he wanted the innerHTML to display as two decimal places.
If he used your first version of rounding, then if the answer happened to be 57.00
it would only display as 57
, with no decimals. So the mathematical rounding doesn't do any good for display purposes.
So I *did* answer him:
( standard_premium*excessPremium_Percent ).toFixed(2);
