I think the maximum integer in python is available by calling sys.maxint
.
What is the maximum float
or long
in Python?
This question is related to
python
int
long-integer
max
For all practical purposes, and with no import at all, one can use:
x = float("inf")
More detail on this related question: How can I represent an infinite number in Python?
For float
have a look at sys.float_info
:
>>> import sys
>>> sys.float_info
sys.floatinfo(max=1.7976931348623157e+308, max_exp=1024, max_10_exp=308, min=2.2
250738585072014e-308, min_exp=-1021, min_10_exp=-307, dig=15, mant_dig=53, epsil
on=2.2204460492503131e-16, radix=2, rounds=1)
Specifically, sys.float_info.max
:
>>> sys.float_info.max
1.7976931348623157e+308
If that's not big enough, there's always positive infinity:
>>> infinity = float("inf")
>>> infinity
inf
>>> infinity / 10000
inf
The long
type has unlimited precision, so I think you're only limited by available memory.
If you are using numpy, you can use dtype 'float128' and get a max float of 10e+4931
>>> np.finfo(np.float128)
finfo(resolution=1e-18, min=-1.18973149536e+4932, max=1.18973149536e+4932, dtype=float128)
sys.maxint is not the largest integer supported by python. It's the largest integer supported by python's regular integer type.
