Something that happened to me the other day -- rounding on the 5th value after the decimal point.

Ruby code that was tested:

puts "%.2f" % 1.234
puts "%.2f" % 1.235
puts "%.4f" % 1.23523
puts "%.4f" % 1.23525

The last value should be 1.2353 (at least that is what i learnt in my maths classes)

info: Using ruby 1.9.2 p0
1.23
1.24
1.2352
1.2352 ## Wrong

info: Using ree 1.8.7 2010.02
1.23
1.24
1.2352
1.2352 ## Wrong

info: Using ruby 1.9.2 preview3
1.23
1.24
1.2352
1.2352 ## Wrong

info: Using ruby 1.8.7 p174
1.23
1.24
1.2352
1.2352 ## Wrong

info: Using jruby head
1.23
1.24
1.2352
1.2353 ## Correct!

So it seems that Java is simply the language to be using ;)
