Does Python have a function to reduce fractions?
The fractions module can do that
>>> from fractions import Fraction>>> Fraction(98, 42)Fraction(7, 3)There's a recipe over here for a numpy gcd. Which you could then use to divide your fraction
>>> def numpy_gcd(a, b):... a, b = np.broadcast_arrays(a, b)... a = a.copy()... b = b.copy()... pos = np.nonzero(b)[0]... while len(pos) > 0:... b2 = b[pos]... a[pos], b[pos] = b2, a[pos] % b2... pos = pos[b[pos]!=0]... return a... >>> numpy_gcd(np.array([98]), np.array([42]))array([14])>>> 98/14, 42/14(7, 3)
Addition to John's answer:
To get simplified fraction from a decimal number (say 2.0372856077554062)
Using Fraction gives the following output:
Fraction(2.0372856077554062)#> Fraction(4587559351967261, 2251799813685248)To get simplified answer :
Fraction(2.0372856077554062).limit_denominator()#> Fraction(2732, 1341)
