What is the smallest number which can be represented in python?
I have seen as small as 2.05623357236e-296 but can there be any smaller?
解决方案>>> import sys
>>> sys.float_info
sys.float_info(max=1.7976931348623157e+308, max_exp=1024, max_10_exp=308, min=2.225073858507e-308, min_exp=-1021, min_10_exp=-307, dig=15, mant_dig=53, epsilon=2.220446049250313e-16, radix=2, rounds=1)
From the docs
min DBL_MIN minimum positive normalized float
min_exp DBL_MIN_EXP minimum integer e such that radix**(e-1) is a normalized float
On my system it is mentioned as min=2.225073858507e-308
