Hello Mark,
I discovered this using asynFloat64 device support (with modbusTCP driver), then made a specific test with Raw Soft
Channel and finally looked in the code of the ao record and in the convert function there is a cast to (epicsInt32) ...
Regards
Christophe

Conversion to epicsInt32 is not normally part of the operation of the ao record. What device support are you using?
Mark

Subject: Rounding in conversion of ao record
Hi people,
There is a rounding operation (cast to (epicsInt32)) when using the conversion of the ao record,
hence, with this conversion only integer is output, no float ...
This is surprising and not equivalent to what is done for the ai record.
Could this be changed ?
Regards,
Christophe
