Last Updated :

With the help of sympy.trailing() method, we can count the number of trailing zero digits in the binary representation of a given number, i.e. determine the largest power of 2 that divides that number.
Syntax:
trailing(n)
Parameter:
n – It denotes the number for which the largest power of 2 that divides that number is determined.
Returns:
Returns the largest power of 2 that divides the given number.
Example #1:
from sympy.ntheory.factor_ import trailing
n = 64
trailing_n = trailing(n)
print("The largest power of 2 that divides {} is 2^{}.".
format(n, trailing_n))
|
Output:
The largest power of 2 that divides 64 is 2^6.
Example #2:
from sympy.ntheory.factor_ import trailing
n = 130
trailing_n = trailing(n)
print("The largest power of 2 that divides {} is 2^{}.".
format(n, trailing_n))
|
Output:
The largest power of 2 that divides 130 is 2^1.
