Hello,

I'm using simulink and I need to convert from a single to a uint16.

Could a kind soul kindly explain why the output of a single (with range 0-2pi) equates to an uint16 of zero?

Here is an example:

And here is the output of that example:

There are a number of uint16 signals in my model with range 0-4000 (I am reading from sevreral ADC). All behave as expected. Just this conversion, in this instance.

Thanks Daniel, Walter. The signal is being output to a host model using a data serial output. The data serial output transmits two signals of type uint16. An example from the mcb;

Yes, I'm using data type conversion block. Sending multiple signals (more than 2), using PU units / a different data type would be preferable.

I still continue to see scaling during data type conversions. This seems very unusual.

Ex. Scaling from 0-1 to 0-4045

Hi Jamie,

I am assuming that you have used "Data Type Conversion" block, and the conversion to "uint16" resulted in unexpected values due to the default integer rounding mode being set to "floor" in Block Parameters. If you change the rounding mode to "round," you will achieve the expected results when converting from "single" to "uint16".
