"G" Format for Floating Point

Prints floating-point numbers exactly like C's printf("%g", value), using a Display implementation.

By default, formatting is done in pure Rust (no dependencies, works on all platforms including Windows and WASM). Enable the libc feature to delegate to your system's snprintf() instead (only available on Unix).

Usage

Use the crates.io repository; add this to your Cargo.toml along with the rest of your dependencies:

[dependencies]
gpoint = "0.3"

To use the libc-based implementation on Unix:

[dependencies]
gpoint = { version = "0.3", features = ["libc"] }

Then wrap your f32 or f64 with a GPoint:

use gpoint::GPoint;

println!("answer: {}", GPoint(42.));

See the API documentation for further details.
