When a double is turned into a string, it is not represented by scientific notation

When parsing JSON strings with Gson, I often automatically convert the contents of string to double, and also scientific notation, which is not scientific, write a method, format it.

     Public Staticstring parsestring (Object str) {string returnvalue= ""; Try{returnvalue=NewBigDecimal (string.valueof (str)). toString (); if(Stringutils.endswith (ReturnValue, ". 0") ) {returnvalue= Stringutils.removeend (returnvalue, ". 0"); }        } Catch(Exception e) {returnvalue=objectutils.tostring (str); }        returnreturnvalue; }

This method can be divided into two cases, if it is a number, it is converted to a number that is not scientifically counted, and if a decimal point is added, the decimal point is removed, and if it is a string, it is converted to a string intact. Get!
