My brother uses a variable of type INT. When this variable reaches a preset value, 80% of this variable is taken.

I use a variable of type INT. When this variable reaches a preset value, 80% of this variable is taken. My approach is int = int * 0.8. Why ca n’t I convert implicitly?

maggic

i = (int) i * 0.8

Is such that
i = (int) (i * 0.8);
or
i = Convert.ToInt32 (i * 0.8);

tietie

i = i * 4/5;

It seems that there is no need to switch, and the efficiency is much better.

Just use the double type

cqgang

double d = i * 0.8

0.8 is a double type... it seems that this is implicitly inconvertible
