epsilon

python numpy machine epsilon Question: I am trying to understand what is machine epsilon. According to the Wikipedia, it can be calculated as follows: def machineEpsilon(func=float): machine_epsilon = func(1) while func(1)+func(machine_epsilon) != func(1): machine_epsilon_last = machine_epsilon machine_epsilon = func(machine_epsilon) / func(2) return machine_epsilon_last However, it is suitable only for double precision numbers. I am interested …

Value for epsilon in Python Question: Is there a standard value for (or method for obtaining) epsilon in Python? I need to compare floating point values and want to compare against the smallest possible difference. In C++ there’s a function provided numeric_limits::epsilon( ) which gives the epsilon value for any given data type. Is there …
