Hi all
i am trying to use round method if have a value 2.08 i want it as 2.1 and
it worked in 1.9.2 but not in 1.8.7 is there any other way of doing it.
USING 1.9.2
1.9.2p320 :001 > 2.08.round(1)
=> 2.1
1.9.2p320 :002 > 2.04.round(1)
=> 2.0
USING 1.8.7
irb(main):001:0> 2.08.round
=> 2
irb(main):002:0> 2.08.round(1)
ArgumentError: wrong number of arguments (1 for 0)
from (irb):2:in `round''
from (irb):2
from :0
i can able to use round but not with one decimal
Can any tell how can i get round(1) in 1.8.7
Cheers,

Hi Keerthi,
Following is useful for you
(2.3465*100).round / 100.0
Note: Don''t forget .0 for 100
Thanks & Regards,
Vijay
