If `α` or `β` is `NaN`, the function returns `NaN`.
Parameters
----------
α: number
First shape parameter.
β: number
Second shape parameter.
Returns
-------
out: number
Differential entropy.
Examples

> v = {{alias}}( 8.0, 2.0 )
~-0.795
> v = {{alias}}( 1.0, -0.1 )
NaN
> v = {{alias}}( -0.1, 1.0 )
NaN
> v = {{alias}}( 2.0, NaN )
NaN
> v = {{alias}}( NaN, 2.0 )
