This is a type class for types with n-roots. The value returned by
nrootandsqrtare only guaranteed to be approximate answers (except in the case ofReal).Also, generally
nroots wherenis even are not defined for negative numbers. The behaviour is undefined if this is attempted. It would be nice to ensure an exception is raised, but some types may defer computation and testing if a value is negative may not be ideal. So, do not count onArithmeticExceptions to save you from bad arithmetic!
