Subject: [PATCH] Fix formatting of SolutionArray columns that are all integers

Make it explicit that these should be printed as integers. Behavior of {fmt}
is different between 6.1.2, which always includes a decimal digit when the
input type is double if no other formatting specifier is provided, and later
versions which format integral doubles as doubles.

Fixes #1526
