@CONVERT

@CONVERT[input, output, value]:  Converts a numeric string (value) from 
one number base (input) to another (output).  Valid bases range from 2 to 
36.  The value must be a positive number between 0 and 2**32-1 
(2,147,483,647).  No error is returned if value is outside that range. 
 For example, to convert "1010101" from binary to decimal, use this 
syntax: 

        %@convert[2,10,1010101]
