This fixes 1.000..7 but does not fix two other cases I didn't mention,

arda:~/cur/ruby> ./ruby -e 'puts 1.00000000000004.to_s'
1.00000000000004
arda:~/cur/ruby> ./ruby -e 'puts 1.000000000000004.to_s'
1
arda:~/cur/ruby> ./ruby -e 'puts 1.0000000000000004.to_s'
1.0
arda:~/cur/ruby> ./ruby -e 'puts 1.99999999999999.to_s'
1.99999999999999
arda:~/cur/ruby> ./ruby -e 'puts 1.999999999999999.to_s'
2
arda:~/cur/ruby> ./ruby -e 'puts 1.9999999999999999.to_s'
