[Tutor] Fraction - differing interpretations for number and string

[Jim Mooney]

Why does Fraction interpret a number and string so differently? They come
out the same, but it seems rather odd

>>> from fractions import Fraction
>>> Fraction(1.64)
Fraction(7385903388887613, 4503599627370496)
>>> Fraction("1.64")
Fraction(41, 25)
>>> 41/25
1.64
>>> 7385903388887613 / 4503599627370496
1.64
