[Pkg-rust-maintainers] Bug#979002: rust-libm: autopkgtest failure on i386: 1.10009765625 is not equal to 2.0

[Paul Gevers]

Source: rust-libm
Version: 0.2.1-2

Dear maintainer(s),

You recently added an autopkgtest to your package rust-libm, great.
However, it fails. Currently this failure is blocking the migration to
testing [1]. Can you please investigate the situation and fix it?

I copied some of the output at the bottom of this report.
