Description

Description of the issue (or feature request).

Add support for negating a complex number.

Package name: @stdlib/math/base/complex/negate
Alias: cneg

Behavior:

var v = cneg( re, im );
// returns [ -re, -im ]

The implementation is trivial; however, in ES6 envs, this is useful when combined with destructuring.
