How to convert large float values to int?
(2 answers)
Closed 1 year ago.
Why does variable 'a = 123465789123456789' have a different value than variable 'b = int(123456789123456789.0)'?
Because python’s float (like in any other language) have a limit in precision, and you’ve reached it. On contrary, python’s integer type is of arbitrary precision, meaning that you’ll never reach its limit.

Sorry if this is a stupid question I am still very new to python but I was wondering,
If I have string, s = '1+6.3+3-7.6'
how could I take the sum of that?
I have tried using isdigit() but that just gets all the digits
I have also tried turning it to a float but I got could not convert string to float
I also tried turning it into an integer but I got invalid literal for int() with base 10.

Closed last year.
a="ab d"
b="ab d"
print(id(a))
print(id(b))
sometimes it is getting interned, sometimes not. What is the general rule for interning of a string in version 3.9 of python.
and are float also get interned or not. I am getting different result every time for this too.
c=3.02
d=3.02
print(id(c))
print(id(d))

I've learnt that python supports very large numbers with int itself.
But in this case :
print(int(12630717197566440579/10))
My answer is
1263071719756644096
and not
1263071719756644057
As it's supposed to be.
Can someone tell me why?

i tried the below code but I am not getting the reason why it is happening?
x=2
y=2
print(id(x),id(y))
in above I have got like below
140732101468592 140732101468592
but if I tried with the float type data like below
x=2.0
y=2.0
print(id(x),id(y))
I have got the output like below
2226214428496 2226204728400
why am I getting same id for integer variable with same value but not for float variable with same values?
The id() function returns identity of the object. As you mentioned, floats and integers are different objects in Python.

Maximum and Minimum values for ints

What is the maximum float in Python?
(4 answers)
Closed 4 years ago.
I use python3.x,I want to know the scope of numerical type.
For example, the float, the maximum and the minimum.
I know the scope of java's float and int, but in python I can't find it now.
For example,java float from 10^-38 to 10^38,so python's float?
int and float are the names of built-in types and are always in scope in Python. I don't know what you mean by "the maximum and the minimum" but max and min are built-in functions, thus always in scope.
