Take the decimal part of a number in mapping

Question

Hi,
If I receive a value as 123,456 and I need to map the integer number to FIELD1 and the decimal number to FIELD2 as this:
FIELD1=123
FIELD2=456
Can I do this without using UDFs?

Answer 1

Hi,
        I don't think this is possible with standard text functions, as inputs to substring function are constants. You definitely need an UDF here.
String splitNumber(String s,int part,Container container)
          String a[]=new String[2];
          a[0]=a[1]="";
          char decimalSeparetor=',';
          try
               int i=0,j=0,l;
               for(l=s.length();i<l && s.charAt(i)!=decimalSeparetor;++i)
                    a[j]=a[j]+s.charAt(i);
               for(j=1,i=i+1;i<l;++i)
                    a[j]=a[j]+s.charAt(i);
          catch(Exception e)
               e.printStackTrace();
          return a[part];
The UDF has two inputs as shown below
113,567 -------->splitNumber("113,567",0)    ---------->   113 (output)----->FIELD1
113,567--------->splitNumber("113,567",1)   ------------> 567 (output)------>FIELD2
113567---------->splitNumber("113567",0)----------------->113567 (output)-------->FIELD1
113567---------->splitNumber("113567",1)-----------------> no output ------>FIELD2
The value of integer part (to be supplied as constants) decides which whether you need the part of number before(0) the decimal separetor or after (1).
