But what does the to function do, exactly? I'd prefer to use one of floor,
round or ceil. Wouldn't you? I'm sure they are available as well.
I could perhaps have found a better example than rounding conversions
since there are so many ways to perform those. But that is beside the
point, which was that safe type conversions should be clearly separated
from unsafe ones.
Regarding your question, currently I think std.conv.to just checks for
over-/underflow and performs a cast. :) If such casts were to be
disallowed, it would of course need to be rewritten.
In any case, the documentation for both cast and std.conv.to should say
which rounding mode is used.
