Take a look at the help concerning

1) display formats (whelp format)

and 

2) numeric storage types and precision (whelp datatype)

Even if your variable was type double (2 byte storage), you would not
get the 18 digits of precision you desire.  You will need to store such
a number as a string variable to retain all 18 digits.
