Expected result

This application increases a non-even floating point number in steps of 0.1 starting from from 1234567.0 / 1024.0 ~= 1205.631835938. For each step it checks if the sum minus its 'floored' values is less than 1.0 (which it should always be by definition of floor).

Background

This test was introduced due to an error for floating point handling in an older newlib version.

The idea for this test is taken from: http://sourceware.org/ml/newlib/2010/msg00149.html
