You mean 1 decimal place after the point? Like 13.4 or 2333.4. I'll go with yes.
If you want to obtain the value with 1 decimal place after the point, then you should do this
double x = some value;
double y = x = int(x*10)/10.0;
this will however not round the number, that is,
if x were 14.39 y would be 14.3, not 14.4
if you want to round it, then you should do this
y = int((x+0.05)*10)/10.0
in this case if x is 14.39 then y will be 14.4
If you do not need the value, but you just need to stream/output the value with 1 decimal place, it's easier, that is
