rust convert a string (with decimals) to a floating point number.
To convert a string with decimals to a floating point number in Rust, you can use the parse
method from the str
type, followed by the unwrap
method to handle potential errors. Here's an example:
fn main() {
let num_str = "3.14";
let num: f64 = num_str.parse().unwrap();
println!("The parsed number is: {}", num);
}
In this example, the parse
method is called on the num_str
string, and it attempts to convert it into a floating point number. The unwrap
method is used to handle any errors that may occur during the parsing process. Finally, the parsed number is printed using println!
.
I hope this helps!
