Missing values occur after converting data type.
显示 更早的评论
Problem :
From the figure above, I calculated by using data type as double.
And when I convert the data type from double to uint16, the value before and after data type conversion block are not same even if there is no process.
Questions :
Can you explain the reason and solution for this problem?

integer rounding mode Floor, i guess
you value might be 4-eps
change it to round (i dont know if that's an option but i think it should be)

your value might be a bit smaller than 4 and it's not showing it because of the format
for example, type following in cmd
4 - 1e-15
ans =
4.0000
Now type
format long
4- 1e-15
ans =
3.999999999999999
floor(ans)
ans =
3

Example above
I tried to convert the data type from double to single before converting to uint16. It can solve the problem.
I think the root cause is the conversion of data types by converting from large data types (double) to small data types (uint16). there is a chance that the value will missing from the conversion.
