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.
