Hi Agustin, BandMathX does not read no-data metadata and handles no-data value just like regular values. It would be a nice feature to add to the application.
In the meantime, you can modify your expression to conditionally ignore those value but it might be a bit tricky since your nodata value is FLOAT_MAX. Have a look at the ManageNoData application or even gdal_translate which can help you with that.

Having an operation such as im1/im2 where both im1 and im2 are tif multi-spectral images with 0 set as no-data value, otbcli_BandMathX complains about "Generated 0 Underflow(s) And 836 Overflow(s)" and the resulting tif image does not have the 3.4028234663852886e+38 value set as no-data (actually, does not have any value set as no-data...). Why? This is inconvenient, is there any way to specify BandMathX to take the no-data values into account so that any operation with a no-data value becomes no-data for a given pixel in a given band?
