Give the command
format long g
and then look at your results again. Do you still observe the "rounding" ?

Please show an example of the rounding you observe and the value you expect.

it makes .65 to 1,-.35 to 0 and many more. the most changing value is 0,after that small negative numbers.u can easily understand for a image if it is destroying 0 value that is black,then i am in big trouble...

use the built_in matlab function for the secant algorithm to find the root of x-2^-x on [0,1] accurate to within 10^-4
