[Numpy-discussion] Time for beta1 of NumPy 1.0 (original) (raw)

I guess this is a change which would just break too much code. And if the default type should by changed for these functions, why not also for array constructors?

On the other hand, many people probably use Numpy almost exclusively with Float64's. A convenient way to change the default type could make their code easier to read. How much effort would it be to provide a convenience module that after importing replaces the relevant functions with wrappers that make Float64's the default?

Regards, Stephan

Please make any comments or voice major concerns A rather minor issue, but I would just like to make sure that a policy decision was made not to move to a float default for identity(), ones(), zeros(), and empty(). (I leave aside arange().) I see the argument for a change to be 3-fold: 1. It is easier to introduce people to numpy if default data types are all float. (I teach, and I want my students to use numpy.) 2. It is a better match to languages from which users are likely to migrate (e.g., GAUSS or Matlab). 3. In the uses I am most familiar with, float is the most frequently desired data type. (I guess this may be field specific, especially for empty().) Cheers, Alan Isaac
