Re: [boost] [Boost-bugs] [ boost-Bugs-1315712 ] Addingboost::is_complex to type_traits.hpp

Uh, where is it?

It was posted to the boost-users list. Implementation is utterly trivial anyway.

There are a number of useful things to go with complex. Here is another.

It is common to need the scalar type that corresponds to a numeric type, whether that type is complex or scalar. For example, the type returned by abs. Implementation is pretty trivial:

Interesting, and good point. OK, is there any objection to is_complex being added, what about Neal's trait (and what to call it if it is added, "scalar" maybe?). John.
