Question

hi,
In interface one field is supposed , Both dollars and cents will be formatted with an implied decimal point before the last  two digits in the data. 
for exm : input is -620.27. then output should be -000062027. Maximum length of the field is 10.

In this way.

Answer 1

Use the replace string function to replace decimal point with null. Then pass the value to a udf.
Write a udf (value cached) and pass the input a= value from Pay_Amount and b - required length of field (10)
public String AddLeading(String a,String b,Container container){
String temp = new String(String.valueOf(Integer.parseInt(a)));
int temp1 = Integer.parseInt(b);
for(int i = 0; (temp1 - a.length()) > i ; i++)
temp = "0" + temp;
return(temp);
