This crate contains floating point types that error if they are set to NaN.

Examples

# fn main() -> Result<(), result_float::NaN> {
use result_float::{rf, Rf64, Result};

fn geometric_mean(a: Rf64, b: Rf64) -> Result<f64> {
    (a * b)?.sqrt()
}

fn mean(a: Rf64, b: Rf64) -> Result<f64> {
    (a + b)? * rf(0.5)?
}

println!("geometric_mean(10.0, 20.0) = {}", geometric_mean(rf(10.0)?, rf(20.0)?)?);
//prints 14.142...
assert!(mean(rf(10.0)?, rf(20.0)?)? == rf(15.0)?);
# Ok(())
# }
