personal opinion, no, it does not make sense. You have to trust your
instincts :-)

yes, one of your problems ;-)

C:\family\ruby>type a1.rb
class TestClass
  attr_accessor :num1
  attr_accessor :num2
  attr_accessor :num3
  attr_accessor :num4
  attr_accessor :num5
  attr_accessor :num6
end

ob = TestClass.new

6.times do |i|
  print "Enter number #{i+1}: "
  eval("ob.num#{i+1}=gets.to_f")          #<---this is your problem?
end

# you have to output your test inputs
6.times do |i|
  print "number #{i+1}: "
  eval("p ob.num#{i+1}")
end

C:\family\ruby>ruby a1.rb
Enter number 1: 2
Enter number 2: 123
Enter number 3: 56
Enter number 4: 78
Enter number 5: 45
Enter number 6: 9999
number 1: 2.0
number 2: 123.0
number 3: 56.0
number 4: 78.0
number 5: 45.0
number 6: 9999.0

[personal opinion] If you have "eval" in your code, there is possibly
something wrong with the way your program is structured...

I think you are testing ruby syntax. Test syntax one-by-one first. Then
connect each slowly... this is my style though... I am a nuby ;-)

In programming, you always ask, why and why not. The two always go together
;-) Again, this is just my opinion... as a nuby...
