The == and eql? return true or false


# the <=> (spaceship operator) returns -1, 0, or 1, 
# depending on whether the first value is equal to the second (0), 
# less than the second (-1), or greater than the second (1).

# Test if two numbers are equal, less than, or greater than each other

puts 12 < 14 #less than
puts 12 < 12
puts 12 <= 12 # less than or equal to
puts 12.0 > 11.9
puts 12.0 >= 12 # greater than or equal to
