[Caml-list] abs min_int

[Caml-list] abs min_int

[Christoph Bauer]

Hi,

the manual describes the function "abs" as

"Return the absolute value of the argument."

This is not quite true:

        Objective Caml version 3.07+beta 2

# abs min_int;;
- : int = -1073741824

IMO abs should thow an Failure exception or the manual should 
point out this behavior.

        Objective Caml version 3.06

# abs (-1073741824);;
- : int = -1073741824
# abs (-1073741823);;
- : int = 1073741823
# print_int max_int;;
1073741823- : unit = ()

1073741824 is larger than max_int;

This is the expected behaviour as documented in the manual.
