Syntax
------ 
LEAST(value1,value2,...)
 
Description
----------- 
With two or more arguments, returns the smallest
(minimum-valued)
argument. The arguments are compared using the following
rules:
If the return value is used in an INTEGER context or all
arguments are integer-valued, they are compared as integers.
If the return value is used in a REAL context or all
arguments are real-valued, they are compared as reals.
If any argument is a case-sensitive string, the arguments
are compared as case-sensitive strings.
In all other cases, the arguments are compared as
case-insensitive strings.
 
LEAST() returns NULL if any argument is NULL.
