Custom function: Decimal to Binary conversion

Here’s a custom function that converts decimal to binary.Feel free to use it and let me know if you find a bug when you use it.It is developed and tested in SAP Data Services 4.2

#input => base 10
$L_next_no = $G_Decimal_input ;
$L_bin_add ='';
$L_bin ='';
while ( $L_next_no  >= 1.0)
begin
  $L_bin = $L_next_no % 2;
  $L_bin_add = $L_bin_add||''||nvl($L_bin,0) ;
  $L_next_no = $L_next_no / 2;
end
#Reverse
$L_len = length($L_bin_add );
$L_ret = '';
$L_CNT = 0;
while ($L_CNT < $L_len )
begin
   $L_CNT = $L_CNT + 1;
   $L_ret = substr($L_bin_add , $L_CNT, 1) || $L_ret;
end
return($L_ret);
