<b>4001.006

s.f. = significant figure or significant digit.
Zeros between digits count as s.f. and digits are s.f.; therefore, this number has 7 s.f.
The second one is a different kind. Leading zeros don't count as s.f.; therefore, this one has only 3 s.f.
Read that site I give you. It explains s.f. VERY WELL. And it isn't hard but you must follow the rules.
