float__min

[Mark NG]

G'day !

I am rather new to mercury and having troubling using float__min (func/0).

I tried to compile this program :-

:- module float_test.
:- import_module io.
:- interface.
:- pred main(io__state::di, io__state::uo) is det.
%--------------------------------------------------------------------%
:- implementation.
:- import_module float.
main -->
        { F = float__min },
        io__print(F).

%------------------------------------------------------------
and got...

float_test.m:015: In clause for predicate `float_test:main/2':
float_test.m:015:   error: ambiguous overloading causes type ambiguity.
float_test.m:015:   Possible type assignments include:
float_test.m:015: F :: float or (func(float, float) = float)


How do I get it to work ??


thanks,
