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:
[dependencies]
gpoint = "0.2"Then wrap your f32 or f64 with a GPoint:
use gpoint::GPoint;
println!("answer: {}", GPoint(42.));
See the API documentation for further details.
