Question

How to check if the given number is neither an infinity nor a NaN in Rust

Answer 1

fn main() {
    println!("f64::is_finite(f64::NAN) = {}", f64::NAN.is_finite());
    println!("f64::is_finite(f64::INFINITY) = {}", f64::INFINITY.is_finite());
    println!("f64::is_finite(0.0) = {}", 0.0_f64.is_finite());
    println!("f64::is_finite(1.0) = {}", 1.0_f64.is_finite());
}


  
/*
run:

f64::is_finite(f64::NAN) = false
f64::is_finite(f64::INFINITY) = false
f64::is_finite(0.0) = true
f64::is_finite(1.0) = true
