Would sind and cosd make Euler's formula work correctly?

sind(x) + i * sind(x) == math.e ** (i * x)

I suspect that adding these functions is kind of like those cartoons where
the boat is springing leaks and the character tried to plug them with their
fingers. Floating point is a leaky abstraction.

Perhaps you'd prefer an enhancement to the fractions module that provides
real (not float) math?
