Significant Figure Rules
Non-zero digits are significant (e.g., 14.2 has 3 sig figs). Zeroes between non-zero digits are significant (e.g., 5.002 has 4 sig figs, 302 has 3 sig figs).
Leading zeroes are never significant (e.g., 0.52 has 2 sig figs).
Trailing zeroes without a decimal point are not significant (e.g., 120 has 2 sig figs, 30,000 has 1 sig fig).
Trailing zeroes with a decimal point are significant (e.g., 340. has 3 sig figs, 3.400 has 4 sig figs).
