max(+Number1, +Number2, -Maximum)

   Unifies the maximum of Number1 and Number2 with Maximum.



Arguments
   Number1             A number.
   Number2             A number.
   Maximum             A variable or number.

Type
   Arithmetic

Description
   This predicate is used by the ECLiPSe compiler to expand evaluable
   arithmetic expressions.  So the call to max(Number1, Number2, Maximum)
   is equivalent to

	Maximum is max(Number1, Number2)

    which should be preferred for portability.

   In coroutining mode, if Number1 or Number2 are uninstantiated, the call
   to max/3 is delayed until these variables are instantiated.




Modes and Determinism
   max(+, +, -) is det

Exceptions
     4 --- Number1 or Number2 is not instantiated (non-coroutining mode    only).
     5 --- Result is of a different type than the evaluation result.
    24 --- Number1 or Number2 is not of a numeric type.
    24 --- Result is neither a number nor a variable.

Examples
   
Success:
      max(5, 2, 5).
      max(2_3, 3_4, 3_4).
      max(5.0 , 2.0, 5.0).
      max(5, 2.0, 5.0).         (The types are adjusted)
      max(5, 2_0, 5_0).         (The types are adjusted)
Fail:
      max(1, 2, 3).
Error:
      max(A, 2, 6).             (Error 4).
      max(1, 2, 2.0).           (Error 5).
      max(5, 2.0, 5).           (Error 5).
      max(4 - 2, 3, 3).         (Error 24).
      max(5, 2, r).             (Error 24).
