Rounding to two significant digits refers to the practice of expressing a number with only the first two non-zero digits, regardless of its decimal or whole number position. For example, rounding 542,867.21054031 results in 5.4 x 10^5. This method is distinct from rounding to decimal places, which focuses on the number of digits after the decimal point. Understanding significant digits is crucial for precision in scientific and mathematical contexts.
