does 120.00 have 5 significant digits?

its written in the para..

No 120.00 does not have 5 sig figs, cause that can be written a million other ways.

The only time you count a zero after a non-zero number is if it has another non zero number after (the zero).

Thats going to throw off a few more ppl :D

zeros after a number which is after a decimal point count as sig figs
to 3 sig figs 0.01000001 is written 0.0100
