Numbers are everywhere around us. They help us to decide on purchases, to plan our retirement, and to track everything from diet and exercise to services we buy. Numbers in the form of measurements are the lifeblood of industrial inspection. The field of NDT uses numbers to measure every physical phenomenon: electricity, thermal expansion, magnetism, light, pressure, viscosity, and ionizing radiation. For this reason, the NDT inspector needs math. There are several situations in which a
technician may need to round off a measurement datum.
