Ruby round answer to 2nd decimal place?

Learning ruby and want to make a simple string where:

puts "A Honda Fit cost $#{3.98 * 10.6} to fill up."

The answer I'm getting is $42.1879999999995; would like the answer to round to two decimal places.

Thanks for the help.

You don't need to change the model of the data, you can just change the view, printing two decimals:

puts "A Honda Fit cost $%.2f to fill up." % (3.98 * 10.6)

You can also use the Float#round method

puts "A Honda Fit cost $#{(3.98 * 10.6).round(2)} to fill up."
#=> A Honda Fit cost $42.19 to fill up.
