Answer 1

fn main() {
    println!("math.sqrt(0): {:.1}", f64::sqrt(0.0));
    println!("math.sqrt(81): {:.1}", f64::sqrt(81.0));
    println!("math.sqrt(14): {:.1}", f64::sqrt(14.0));
    println!("math.sqrt(-10): {:.1}", f64::sqrt(-10.0));
}

  
    
/*
run:
  
math.sqrt(0): 0.0
math.sqrt(81): 9.0
math.sqrt(14): 3.7
math.sqrt(-10): NaN
