#5782: Failure of __pow__ in RDF for noninteger powers of zero
------------------------------+---------------------------------------------
Reporter: kbaker | Owner: somebody
Type: defect | Status: new
Priority: minor | Milestone: sage-3.4.1
Component: basic arithmetic | Keywords: RDF, __pow__, zero
------------------------------+---------------------------------------------
Positive noninteger powers of RDF(0) give nan rather than zero:
{{{
sage: RDF(0)^.5
nan
sage: RDF(0)^(1/2)
nan
}}}
In contrast, noninteger powers of CDF(0) have the correct value:
{{{
sage: CDF(0)^.5
0
sage: CDF(0)^(1/2)
0
}}}
