tustvold opened a new issue #1177:
URL: https://github.com/apache/arrow-rs/issues/1177
**Describe the bug**
Initially noticed on #1174 but it would appear the formatting changes in
Rust 1.58 have altered the formatting of floating point numbers causing the
tests to fail
**To Reproduce**
Run the `test_convert_double_to_string` test on master, and it will fail with
```
Left: 1e-15
Right: 0.000000000000001
<Click to see difference>
thread 'record::api::tests::test_convert_double_to_string' panicked at
'assertion failed: `(left == right)`
left: `"1e-15"`,
right: `"0.000000000000001"`', parquet/src/record/api.rs:1096:9
stack backtrace:
```
**Expected behavior**
Test should not fail
