var A = "￥4.00";
var B = "￥5.00";

var a = parseFloat(A.replace(/[^\x00-\xff]/g, ''));
var b = parseFloat(B.replace(/[^\x00-\xff]/g, ''));
var c = "￥"+ (a+b);
alert(c);

<input type=button value=click onclick="fnc()">
<script>
var A = "￥4.00";
var B = "￥5.00";
function fnc(){
var sum = "￥" + (parseInt(A.substr(1)) + parseInt(B.substr(1)) + 0.001);
C = sum.substring(0,sum.length - 1);
alert(C);
}
