Subject: private method - Fixnum (NoMethodError)

Dear All,

I can't find the error in my code. Can you explain me "private method
-  Fixnum (NoMethodError)"?

Many thanks in advance,

koko

def subtotal(qty = 1)
	return nil if self.to_f <= 0 || qty.to_f <= 0
	self.to_f * qty.to_f
end

apple = 11

puts apple.subtotal(2)
