But this remains strange to me: 
perl -e 'print  201/10 == 20.10000000000000000 ? "eq" : "ne"'
eq

perl -Mbigrat -e 'print  201/10 == 20.10000000000000000 ? "eq" : "ne"'
eq

perl -e 'print  201/10 == 20.10000000000000142 ? "eq" : "ne"'
eq

perl  -Mbigrat -e 'print  201/10 == 20.10000000000000142 ? "eq" : "ne"
+'
ne

The last two cases is where one can see the difference that bigrat makes, but should the comparison in the second case not yield false?
