Hi,

Please see the numbers as follows:
(1) 5.81`-8.302885470482789*^-6
(2)4.9768530257766464645`6.82698483232164*^-9

I find that the number like (1) with the "-"sign after "`" appears in the form of 0.10^a.

What is the meaning for the "-"sign after "`"? the "-" sign means the number of the effective digitals is less than the precison? Are the only digitals "5.81" in the first value thinked to be correct doing the calculation?


I hope your help. Thanks in advance! Happy New Year!

Shinnie
