This crate exports a macro for asserting that two numbers are approximately equal (`1.0e-6`, by default) to each other.

On panic, this macro will print the values of the expressions with their
debug representations. You can optionally add an optional diff value. If you
don't supply a diff value as an argument, `1.0e-6` is the default used. 

## Usage

To use this crate, add `assert_approx_eq` as a dependency of your Rust project.

Then, you can use the macro as follows:

```rust
use assert_approx_eq::assert_approx_eq;

let a = 3f64;
let b = 4f64;

assert_approx_eq!(a, b); // panics
assert_approx_eq!(a, b, 2f64); //does not panic
assert_approx_eq!(a, b, 1e-3f64); // panics
```

You can read documentation for how to use this crate on [docs.rs](https://docs.rs/assert_approx_eq) or [view the example].
