Dealing with integers illustrates the matter more clearly. When the decimal value is exactly 0.5, then printf should round to the nearest *even* integer, as far as I know, so you should get 0 -> 0 0.5 -> 0 1 -> 1 1.5 -> 2 2 -> 2 2.5 -> 2 3 -> 3 3.5 -> 4 4 -> 4 4.5 -> 4 5 -> 5 Now I realize that Cygwin's printf doesn't get it right, because seq 0 .5 5 | while read x; do printf '%-3s -> %.0f\n' $x $x; done gives 0 -> 0 0.5 -> 1 1 -> 1 1.5 -> 1 2 -> 2 2.5 -> 2 3 -> 3 3.5 -> 3 4 -> 4 4.5 -> 4 5 -> 5 Both Solaris' /bin/printf and Perl's printf() give the right output. In your examples there is also an additional issue, which is how numerical values are represented. Here is Perl: seq .105 .01 .155 | while read x; do printf '%-5s -> %.2f\n' $x $x; done 0.105 -> 0.10 0.115 -> 0.12 0.125 -> 0.12 0.135 -> 0.14 0.145 -> 0.14 0.155 -> 0.15 They all seem correct expect the last one. The reason why 0.155 becomes 0.15 and not 0.16 is that 0.115 can not be represented exactly. It is represented as a number which is slightly *smaller* than 0.155, so it becomes 0.15 after rounding.
