Decimal to fraction?
I did .1/8, and the output was 0.0125000000. Is there a way to get it to display as 1/80.
There are at least three ways to recover a rational from one of its numerical approximations:
sage: a = .1/8 sage: a.simplest_rational() 1/80 sage: a.nearby_rational(0.0001) 1/80 sage: a.exact_rational() 3602879701896397/288230376151711744
You can have a look to their respective documentations to see the differences. And you should understand that the floating point number
a is not equal to 1/80 but to 3602879701896397/288230376151711744 !
