[expr] function available since [Tcl] 8.5:
Converts a number to ''some'' integral type ([int], [wide] or [bignum]).

The name of this function is derived from French, via ALGOL.

[LV] So, this is functionally similar to a cast? What happens when
the number being entiered doesn't fit into the size type? A bignum being
''cast'' into an int, for instance?

''[escargo] 29 Nov 2006'' - It's more like the '''round''' function.
I think the point is that however big the number might be, it will pick
the smallest integral type that will hold it. See TIP 237 for full
details.
