"Value not completely converted"

view story

http://stackoverflow.com – I'm performing some calculations in command line on a Ubuntu console: java <prog1> | unbuffer -p cut -c<some columns> | xargs -I '{}' printf "%d*0.0056\n" 0x{} | bc Output, for example: 5.007123 : value not completely converted Java program outputs a stream of data, so I get this error with each result. Does anyone know how to get rid of this one or the reason for it? (HowTos)
