puts "Fahrenheit to Centigrade Conversion

Input a temperature in Fahrenheit:"

STDOUT.flush

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

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