I worked at a company with a technician who clearly did not understand this. When I asked him to order an assortment of resistors with a range of values, he came back to me and said that Digikey did not have most of them. Turns out he had submitted a request for quote, listing desired values in a linear progression: 1 ohm, 2 ohm, 3 ohm, 4 ohm, etc.
