For earlier discussion, see https://github.com/rust-lang/rust/issues/14339
This issue was labelled with: I-enhancement in the Rust repository
By rounding to a specific number of digits by default, the standard library is causing confusion. Printing to a specified precision is very useful, but it should only happen via {:.2} rather than by default.

Research direction
Start by reading the earlier discussion in Rust issue 14339 and the surrounding standard-library formatting behavior. Define how default floating-point output should use full precision while explicit formats such as {:.2} retain their specified precision; the issue provides no file or test entry point.
