Converting String to the Number

When a Number is rendered as a String in the browser we can convert it to Number using getOANLSServices().stringToNumber method.

String quoteHdrNum = getQuoteContextParam(pageContext, "QotCtxtHdrNum");
java.lang.Number QuotNum= pageContext.getOANLSServices().stringToNumber(quoteHdrNum );
  {
     //do Operation
  }
