+*min(<number>{,<number>...<number>})
+*max(<number>{,<number>...<number>})
+
+Returns the smallest (or biggest) from the set of given numbers.
+
+Example:
+	.@minimum = min(1, -6, -2, 8, 2); // .@minimum will be equal to -6
+	.@maximum = max(0, 5, 10, 4); // .@maximum will be equal to 10
+	.@level = min(BaseLevel, 70); // .@level will be the character's base level, capped to 70
+
+---------------------------------------

 *md5("<string>")
 
 Returns the md5 checksum of a number or string.
