Subject: Make fixed_power also work for data types that have no implicit conversion from int... 
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=520456dae07eb659639a30eea9fa852e05b30794;p=dealii-svn.git

Make fixed_power also work for data types that have no implicit conversion from int by avoiding setting the return value to 1 for N==0 (only N>0 allowed anyway).
