Parsing DecimalFormat to avoid scientific notation

Question

I need parsing a number, String value = "15000000"

Public static String FormatValue(value){
    double formatedValue= Double.parseDouble(value);        

    DecimalFormatSymbols dfs = new DecimalFormatSymbols();
    dfs.setDecimalSeparator('.');       
    dfs.setGroupingSeparator(' ');
    DecimalFormat df = new DecimalFormat("# ### ### ### ###.##", dfs);
    df.format(valorAformatear);
    return  String.valueOf(formatedValue);  
}   

I need the return value to be "15 000 000.00" BUT, When I call the method returns, "7.5E7", how can I avoid the scientific notation?

Answer 1

You ignored the return of the format method and instead returned the normal conversion to a String using String.valueOf . The format method doesn't change the number; it returns its formatted representation. Also, String.valueOf will use scientific notation if the number is large enough.

Just return what format returns.
