The lens aperture is usually specified as an f-number, the ratio of focal length to effective aperture diameter. A lens typically has a set of marked "f-stops" that the f-number can be set to. A lower f-number denotes a greater aperture opening which allows more light to reach the film or image sensor.
In order to keep the original number as 7.877 but make it display 7.9, you need to<u> use the </u><u>rounding off tool</u><u> to round it off to a single decimal place.</u>
