Answers for "python best way to get smallest and biggest number"

smallest possible number in python

The smallest possible number in python (not underflow to 0)
is the smallest possible subnormal number.

# L is the lowerbound exponent given by IEEE754 double precision.
L_sub < (machine_epsilon * 2**L)  =  (2**-52) * (2**-1022) = 2**-1074

Thus, smallest_number = 2*-1074 => 5e-324
