Subject: Use the appropriate type to state a constant.
X-Git-Tag: v9.1.0-rc1~1175^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=refs%2Fpull%2F6531%2Fhead;p=dealii.git

Use the appropriate type to state a constant.

Specifically, make sure that a statement also compiles if we are working with
complex-valued data.
