here's one way:
def fix_qty(qty) if qty.to_i == qty return "%i" % qty else return "%.3f" % qty end end
def fix_price(price) return "%.2f" % price end
qty = [1, 2.0, 3.00, 4.000, 5.001, 6.010, 7.100] price = [1, 2.0, 3.00, 4.001, 5.987, 6.010, 7.100]
qty.each {|q| puts fix_qty(q)} price.each {|p| puts fix_price(p)}
