        }

                                                {
        String dblString = dbl.toString();

        //  System.out.println("Input String:"+dblString);
        String mString = "";
        int exp = 0;

        if (dblString.indexOf("E") > -1) {
            //9.0E-4
            //1.378E05
            exp = Integer.parseInt(dblString.substring(dblString.indexOf("E") + 1));
            dblString = dblString.substring(0, dblString.indexOf("E"));
        }

        int len = dblString.length();

        if (dblString.indexOf(".") > -1) {
            String s = dblString;

            while (s.endsWith("0")) {
                s = s.substring(0, s.length() - 1);
            }

            exp = -s.length() + s.indexOf(".") + 1 + exp;
            mString = s.substring(0, s.indexOf(".")) + s.substring(s.indexOf(".") + 1);

            //System.out.println("Is decimal, mString,exp "+mString+","+exp);
        } else {
            String s = dblString;
            int c = 0;

            while (s.endsWith("0") && !s.equals("")) {
                c++;
                s = s.substring(0, s.length() - 1);
            }

            mString = s;
            exp = c + exp;

            //System.out.println("Is not decimal, mString,exp "+mString+","+exp);
        }

        //System.out.println("Return String "+mString+"E"+exp);
        return mString + "E" + exp;
    }

static String stripBrackets

(

String

in

)

[static]

java.lang.String.replace() won't replace a char with null which is why I have done it this way.

if (in==null || in.equals("")) return null; String out = in.replace('(',' '); out = out.replace(')',' '); return out.trim();

Definition at line 116 of file HDUtil.java.

                                                  {
        if (in == null) {
            return null;
        }

        char[] charArray = (in.trim()).toCharArray();
        StringBuffer out = new StringBuffer();

        for (int i = 0; i < charArray.length; i++) {
            char test = charArray[i];

            if ((test != '(') && (test != ')') && (test != '*') && (test != '\"') &&
                    (test != '\'')) {
                out.append(test);
            }
        }

        return out.toString();

    }

static void toFile	(	String	mystr,
		String	filedir,
		String	filename
	)			[static]

Writes a String to the specified file.

Parameters:

	string
	filedir
	filename

                                                                             {
        try {
            File f = new File(filedir, filename);
            FileWriter fw = new FileWriter(f);
            fw.write(mystr);
            fw.close();
        } catch (IOException e) {
            System.err.println(e);
        }
    }
