Significant Figures

Re: Please adjust significant figures

'Significant figures (also called 'significant digits') is
an idea from the physical sciences that each number has a
precision implied by the digits of its presentation.

Here are some numbers with 3 significant digits, and the
implied precision:

number	implied precision
105	+- 1
31.2	+- 0.1
70.0	+- 0.1
3.35	+- 0.01
1.00	+- 0.01
0.002	+- 0.001

Note that both leading and trailing zeroes AFTER the decimal point
are significant.
