intprom.d(6): Deprecation: integral promotion not done for -s, use
'-transition=intpromote' switch or -cast(int)(s)
What shall I do in order to get my template code
void mymain (T) ()
{
:
b[i] = -b [i];
:
}
compiled for any type for which negation is defined?
b[i] = cast(typeof(b[i]))-b[i];
And then use -transition=intpromote.
Note, your function wasn't real code, so maybe if you have the type of
b[i] somewhere it might look better than what I wrote (like maybe
cast(T)-b[i]).
