Robinhood phone screen - fractional share, rejected

The fractional share edge cases are always boundary precision issues. Did you use float or handle it differently?

Float. Probably should have done decimal arithmetic. Precision loss on the last test I'm guessing.

CoderPad hidden tests catching float precision is rough. Easy to miss without knowing what edge cases they test.
