Hello - Bonjour!
I have encountered unexpected behaviour converting integers to floats:
# let x = 7.;;
val x : float = 7
# let y = float 7;;
val y : float = 7
# x == y;;
- : bool = false
The internal representation of "7." is obviously different to "float 7".
Is there some reason to it? This makes it hard to write things like:
if a_float == float (truncate a_float) ...
if one wants to check whether a float can actually be represented as
an integer...
français:
La représentation de "7." et évidemment differente de "float 7".
Est-ce qu'il y a une raison? C'est un problème si on veut verifier si un
"float" peut être représenté comme "int"...
Regards,
Markus Mottl
