# Description Running ```otbMathParserXTestDriver otbBandMathXImageFilter``` : ``` 1188: The Following Parsed Expression : vcos(2 * pi * im1) div (2 * pi * bands(im2,{1,1,1}) + {3.38,3.38,3.38}) mult vsin(pi * bands(canal3,{1,1,1})) 1188: Generated 99 Underflow(s) And 98 Overflow(s) ``` But test succeeds. # More tests Changing muparserX formula to ```vcos(2 * pi * im1) div (2 * pi * bands(im2,{1,1,1}) + {10,20,30}) mult vsin(pi * bands(canal3,{1,1,1}))``` still have the under/overflow error. Test still passes, without changing expected result computation in ```otbBandMathXImageFilter.cxx```... TODO: investigate this overflow error.
