I know that there exists commands like eps, realmin, realmax etc. Is it possible to obtain complete float information as provided by Python's sys module (see below)? Thanks a lot.

> import sys
> sys.float_info
# output: sys.float_info(max=1.7976931348623157e+308, max_exp=1024, max_10_exp=308, min=2.2250738585072014e-308, min_exp=-1021, min_10_exp=-307, dig=15, mant_dig=53, epsilon=2.220446049250313e-16, radix=2, rounds=1)

Hi Dimitrios,

I Understand that you want to find the limits and entire information of a datatype with a single command, however it is not possible. But you can create MATLAB function to return the structure with necessary fields. Also to know the information of a variable, you can use “whos” command.

Please refer to the MATLAB Documentation to know more:
