floating point print out

[David Grohmann]

I have printed out a floating point number in  format long e
1.00000000000000e-00  which is apparently slightly less than 
1.00000000000000e00
debug> x
ans =  1.00000000000000e-00
debug> x < 1
ans =  1.00000000000000e+00
debug> 1 - x
ans =  1.11022302462516e-16

What is the decimal value for 1.00000000000000e-00 , is it not possible 
to show? entering in the text "1.00000000000000e-00" to an octave prompt 
produces:
debug> 1.00000000000000e-00
ans =  1.00000000000000e+00

I ran the same code on matlab that produced this number and instead got  
9.897959183673469e-001

I know I will need to post the code and I will if I am allowed (and find 
a way to boil the problem down to a small test case). But I'm still 
wondering what 1.00000000000000e-00 means negative zero exponent.  And 
do you believe this is a bug that could be important?

debug> version
ans = 2.9.10
