Cargo Features

[dependencies]
float-cmp = { version = "0.10.0", default-features = false, features = ["std", "ratio"] }
default = ratio

The ratio feature is set by default whenever float-cmp is added without default-features = false somewhere in the dependency tree.

std
ratio default = num-traits

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
