According to the MATLAB documentation, the value of eps should be 2^-52.
“eps returns the distance from 1.0 to the next largest double-precision number, that is eps = 2^(-52).” (from http://www.mathworks.com/help/techdoc/ref/eps.html).
However, when I type eps in MATLAB’s command window, I get eps = 2.2204e-016.
I’m confused. What is the actual value of eps?
Thank you.
Err, on my machine Matlab gives
2^(-52) == 2.2204e-16. Am I missing something obvious in your question ?
