public static boolean IsDoubleValue(String input) {

if(!TextUtils.isEmpty(input.trim())) { //use <em>if(!input.trim().toString().equals("")) {</em> if you are not on the Android platform

String regExp = "[\\x00-\\x20]*[+-]?(((((\\p{Digit}+)(\\.)?((\\p{Digit}+)?)([eE][+-]?(\\p{Digit}+))?)|(\\.((\\p{Digit}+))([eE][+-]?(\\p{Digit}+))?)|(((0[xX](\\p{XDigit}+)(\\.)?)|(0[xX](\\p{XDigit}+)?(\\.)(\\p{XDigit}+)))[pP][+-]?(\\p{Digit}+)))[fFdD]?))[\\x00-\\x20]*";

return input.matches(regExp);

}else{
