Prints floating-point exactly like a `printf("%g", value)`, using a `Display` implementation via `libc`'s `printf()`'s .
Use the crates.io repository; add this to your `Cargo.toml` along
with the rest of your dependencies:
```toml
[dependencies]
gpoint = "0.2"
```
Then wrap your `f32` or `f64` with a `GPoint`:
```
use gpoint::GPoint;
println!("answer: {}", GPoint(42.));
```
See the [API documentation](https://docs.rs/gpoint) for further details.
