However, in the normalized form of that notation, placeholder leading and trailing digits do not occur, so all digits are significant. The significant figures also known as the significant digits and decimal places of a number are digits that carry meaning contributing to its measurement resolution. When taking antilogarithms, the resulting number should have as many significant figures as the mantissa in the logarithm. Exact values, including defined numbers such as conversion factors and 'pure' numbers, don't affect the accuracy of calculation. The abbreviation s. Skip to main content. Please remember that, in science, all numbers are based upon measurements except for a very few that are defined. For example, if a ruler's smallest mark is 0.
