illegal radix 0

[Insectoid]

I'm getting an error 'illegal radix 0' in my (rather inefficient and messy) bin/octal => decimal converter on this line:

Ruby:

#base is the base of the number (base, 2, base 8, etc.) #temp is an integer of base temp.to_s.length.times do |i|     answer += (temp.to_s(i).to_i) * (base^i) end

code:

irb(main):002:0> 15.to_s 0 ArgumentError: illegal radix 0         from (irb):2:in `to_s'         from (irb):2

^ is XOR. ** is exp

code:

irb >> 2^2 => 0 >> 2**2 => 4

insectoid;

to_s wants a base to convert to.

Starts at 2.
try irb and

code:

btiffin, you have just completely nullified the entire purpose of this project by telling me this. Thanks. (sarcasm heavy there). But thanks, that will help me out.

just because there's a build in method, does not mean that you can't rewrite it for practice anyway. Better yet, now you have a method to spec against.

[btiffin]

I agree with Tony. And as he pointed out, you should practise. (things like ^ vs **).

10,000 hours is a lot of hours. And we need more experts. Not that you may want to be an expert at Ruby ... but I'll advise anyone to pick a few topics and struggle to level of expert.

Knowing full well that any given human only gets to pick 1, 2 maybe 3.

Yeah, Ruby is one I want to master. I didn't mean that I'm not going to do it because there's already a method, rather that when it's done, it will remain rather useless.

I want to master Ruby, Java, and one of the C's (Java, just because it's so stupid I want to be able to say, ha! I beat you!)

Useless code is what education is all about!
