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
i can able to use round but not with one decimal
It is no good saying "it did not work". Show us what you did and what
the result was and what you expected. Copy/paste it from the console
so we can see exactly what happened.
