Hi there,

  I have been facing problem in displaying the value of the column which
is of type float. by default it displays only single digit after decimal
point so how can I set the precision while displaying the value of the
field in the rhtml file

    thanking you

You need to format it yourself as in:

<%= '%.2f' % [your_value] %>

Compare:
 >> '%.2f' % [4.5]
=> "4.50"
 >> 4.5.to_s
=> "4.5"
