I'm trying to understand the rounding function in the floating point notation. Rounding to the nearest interger seems to work according to documentation with x.50 rounding up if x is odd and truncating if x is even. The difficulty I'm having arises when I round to the tenths place with something like - $rounded=sprintf ("%.1f",$r); I get the following results: 3.05 is 3.0, 3.15 is 3.1, 3.25 is 3.2, 3.35 is 3.4, 3.45 is 3.5, 3.55 is 3.5, 3.65 is 3.6, 3.75 is 3.8, 3.85 is 3.9, 3.95 is 4.0. I realize I could write a subroutine to do it correctly, but I really would like to know what's going on. Any ideas? Thanks
