Merge #28

28: Avoid change in float rounding behaviour in tests r=Nemo157 a=Nemo157

rust-lang/rust#102935 changed the behaviour of `format!("{:.0}", 0.5)` to round to 0 instead of 1 for consistency. The test case I copied from `std` was using this, so change to using 1.5 which has the same behaviour on stable and nightly.
