UDF or Standard function

Question

Hi All,  
My scenario is Soap to RFC . A field  by name ,Number , value may get a whole number or a decimal value.
The length of the field is 18.
If the value is a whole number then it should be with leading Zeros
EX:
A)    Input :1234 Output :000000000000001234
If the value is a decimal number  and then the output should be as such
B)    Input:123.45   Output:123.45
Could any one help me out,to find whether the input value is decimal or whole number
Thanks in Advance

Hi,
   you can try this UDF
public static String checkEmptyField(String s) {
          try
               if(s!=null)
                    s=s.trim();
               try
                    s=new Integer(s).toString();
                    int l=s.length();
                    for(int i=0;i<18-l;++i)
                         s="0"+s;
               catch(NumberFormatException e)
                    s=new Double(s).toString();
          catch(Exception e)
               return s;
          return s;
inputs ->1234,2.3,null
corrosponding outputs->000000000000001234,2.3,null
