» Significant Figure Rules 01 >> 02 >> 03 >> 04 >> 05 >> All nonzero digits are significant. Zeros that appear between other nonzero digits are always significant. Zeros that appear in front of all of the nonzero digits are called left-end zeros. Left-end zeros are never significant. Zeros that appear after all nonzero digits are called right-end zeros. Right-end zeros in a number that locks a decimal point are not significant. ▬▬▬ 美銀銀時 ☐☐ Right-end zeros in a number with a decimal point are significant.
