The last digit in any number is referred to as the estimated digit. In science, all other numbers are considered significant digits because they are precise measurements.
Know MoreThe last number in a measurement in science is simply an estimation. For example, if a metal rod measures slightly over 234 inches, the final measurement can be rounded so the answer is 234 instead of 234.2.
