Here are my code and its showing 00.000.000.00. I have changed this code another way then it's showing only the first digit of the result.
$(document).on('change', '.prc', function() {
var tSum = 0;
$('.prc').each(function() {
tSum += parseFloat($(this).val());
});
$('.totalprc').val(tSum);
});

<input class="prc" value="0.00" />
<input class="prc" value="0.00" />
<input class="prc" value="0.00" />
<input class="totalprc" />
