If I want to get the value of sqrt(10001),and it should to be 100.00499...
However, MATLAB shows 100.005.
How should I write the code to get 100.00499...
THANK YOU

Matlab is simply truncating the displayed value for ease of reading.
format longG
sqrt(10001)
In both cases, the actual value matlab holds in memory is within +/- epsilon of the true value. Epsilon can be calculated like so:
eps(sqrt(10001))
