In reading the numbers back, they are being rounded to 18 decimal digits of precision:
use warnings; for(10.1, 10.2, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8, 10.9) { printf "%.18g\n", $_; } __END__ Outputs: 10.0999999999999996 10.1999999999999993 10.3000000000000007 10.4000000000000004 10.5 10.5999999999999996 10.6999999999999993 10.8000000000000007 10.9000000000000004
I don't know why that is happening or how to influence the result, but you clearly want those numbers to be rounded to 3 decimal digits of precision:
use warnings; for(10.1, 10.2, 10.3, 10.4, 10.5, 10.6, 10.7, 10.8, 10.9) { printf "%.3g\n", $_; } __END__ Outputs: 10.1 10.2 10.3 10.4 10.5 10.6 10.7 10.8 10.9
