This package contains some basic utilities for working with `Float` values in
[Elm](http://elm-lang.org). The current (very limited) API can be summed up by a few of
the examples from the docs:

```elm
import Float.Extra as Float

Float.equalWithin 1e-6 1.9999 2.0001
--> False

Float.equalWithin 1e-3 1.9999 2.0001
--> True

Float.interpolateFrom 5 10 0.6
--> 8

Float.interpolateFrom 10 5 0.1
--> 9.5
```

Currently the only functions that have been implemented are ones that were
needed by the `elm-interval` and `elm-geometry` packages, but I'm happy to
consider pull requests for other generally-useful functionality. Please
[open a new issue](https://github.com/ianmackenzie/elm-float-extra/issues)
before starting work, though, so we can discuss different approaches!
