[Numpy-discussion] "boolean" type

[Ivan V. i B. <iv...@ca...>]

Hi all,

Since there is a "string" type which is the same as "str_", how come
there is no "boolean" type which is the same as "bool_"?  Did I miss
some design decision about naming?  You know, just for completeness, not
that it is some kind of problem at all! ;)

Cheers,

Well ...

>>> import numpy
>>> numpy.__version__
'0.9.9.2852'
>>> numpy.bool_
<type 'boolscalar'>

Sorry if I didn't make my question clear.  What I find lacking is a
``numpy.boolean`` type which is to ``numpy.bool_`` the same as
``numpy.string`` is now to ``numpy.str_`` (i.e. a pure reference with a
prettier name).  Otherwise I'm not getting what you're meaning! C:)

Ok, so maybe it is because it is called "bool8" ? So that it is clear
that it takes 8 bits ?
