Product Class #2

Ruby
1

I was wondering if anyone had any ideas on how I could make the
following
method "return “$#{@price}0” if “@price” only has one 0 after the “.”,
and
just "return “$#{@price}” if it has two?
Thanks.

(The following method is inside a class called “Product”… Hence the
subject)

def price
    if @price.to_s.length == 4
        return "$#{@price}"
    else @price.to_s.length
        return "$#{@price}0"
    end
end

“$%.2f” % @price

Note though that for accuracy reason it’s best to store currency as an
int of
cents, not a float of dollars so then it would look like this:
“$%d.%02d” % @price.divmod(100)

Sorry, I’m a beginner at Ruby(Not at programming though…)
Could you show me that in the method?
Thanks.

Thanks.
In both cases you can turn the snippet into a method by putting “def
foo()” in
front of it and “end” behind it. That’s all there is to it.
