Hi! I'm a novice in MATLAB. I have a simple problem:
> x=9.459012348 > y=9.459012347
> x-y
ans =
1.000000082740371e-009
Hmmm... Why I get that "...82740371"? Thank you very much.

FAQ 6.1
x-y cannot be represented exactly in binary form, thus it approximates the result.

Thank you. Now it's all clearer.
But I'm still not able to figure how EPS is involved :\
