Collecting TC measurements with nidaqmx python module - rounding decimal place during measurement

[ElliottMagnuson]

I've been following this (https://www.youtube.com/watch?v=NMMRbPvkzFs) video to use the python nidaqmx module to collect TC measurements with a cDAQ-9172 chassis and 9211 card.

The following code is directly from the video (except I'm using my own DAQ):

with nidaqmx.Task() as task:

    task.ai_channels.add_ai_thrmcpl_chan("cDAQ1Mod3/ai3")

    while i < 30:

        data = task.read()

        print(data)

This prints out temperature values like this:

24.983256110305593

Does any one know if there is built in support via the module to round the collected data point down to 24.98? I can do this downstream if really need be, but I am specifically interested in knowing if I can record data points at 2 decimal places with the nidaqmx module instead.

thanks!

Probably not. The API will return the data as a double precision floating point value. You'll have to do whatever kind of formatting you want later on, as suspected.
