Hello,I can use a script like: #!/bin/bash x=3.7 # pass variable x to awk via -v (var=value) awk -v x=$x 'BEGIN { printf "%3.0f\n", x }' # which returns the value 4 as expected, but are there any other methods that can be used?
In bash this must be a string (bash uses only fixed width integers for numbers), so you can put as many decimal places as you like. awk will treat it as a string or floating point number, depending on context. The f output format forces conversion. Another way is to do arithmetic; even x+0 will do it. IIRC, all numbers in awk are doubles (IEEE 64-bit floats). The documentation on awk can tell you more about conversions, rounding, etc. Regards -- Eliot Moss -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
