How would I raise a number to a power in a SELECT statement computed
column?

I have tried the "^" and the "**" operators with no success. I receive
SQL engine error #221: The syntax for an expression or restriction
clause is invalid.
 
E.g., 

select ( 10 ^ 6 ) as Test 
 from TestTable;

I have also not found any documentation for this on Pervasive
web-site.
