UDEC

 The UDEC function returns a character-string value that  is  the
 unsigned  decimal  equivalent  of  the specified parameter.  The
 return value is compatible with all other string types.


 Syntax:

    UDEC(x [[,length[[,digits]]]])


 The parameter 'x' is the expression to be converted.   The  UDEC
 function  can  take  a  parameter  of any type except VARYING OF
 CHAR, conformant parameters, or  schema  types.   This  function
 requires the size of 'x' to be less than or equal to the size of
 INTEGER64 (if supported) on your system.  If  your  system  does
 not  support INTEGER64, then the UDEC function requires that 'x'
 be less than or equal to the size of INTEGER32.

 Two optional  integer  parameters  specify  the  length  of  the
 resulting string and the minimum number of significant digits to
 be returned.  If you specify a length that is too short to  hold
 the  converted  value,  the resulting string is truncated on the
 left.

 If you do not specify values  for  the  optional  parameters,  a
 default  length  and  a  default  minimum  number of significant
 digits is used.  If the size of 'x'  is  greater  than  32,  the
 defaults  are 21 characters for the length and 20 characters for
 the minimum number of digits.  Otherwise, the  defaults  are  11
 characters  for  the  length  and  10 characters for the minimum
 number of digits.
