--- Comment #1 from AndyC <andy at squeakycode.net> ---
Tested on DMD v2.066.1, this runs fine.

import std.string;

void main()
{
    assert(format("%.1f", 0.09) == "0.1"); // Failed, formatted as "0.0"
    assert(format("%.1f", -0.09) == "-0.1"); // Failed, formatted as "-0.0"
    assert(format("%.1f", 0.095) == "0.1"); // OK
    assert(format("%.1f", -0.095) == "-0.1"); // OK
    assert(format("%.1f", 0.094) == "0.1"); // Failed, formatted as "0.0"
    assert(format("%.1f", -0.094) == "-0.1"); // Failed, formatted as "-0.0"
}


Report was on windows, I tested in on linux, hopefully format() isnt os
specific.
Report mentions std.format.formatValue but doesnt test it.
