puts <<ENDINTRO
Fahrenheit to Centigrade Conversion
-----------------------------------
Input a temperature in Fahrenheit:
ENDINTRO
STDOUT.flush

ftemp = gets.chomp.to_f
ctemp = ( (ftemp - 32) / 1.8 )

puts "", "#{ftemp} F is #{ctemp.round} C."
puts "#{ftemp} F is %d C." % ctemp
puts "#{ftemp} F is %.2f C." % ctemp

rounded_ctemp = format( "%.2f", ctemp )
puts "#{ftemp} F is #{rounded_ctemp} C."
