Submitted by Nidhi, on October 08, 2021

Problem Solution:

In this program, we will convert a string into float using the parse() and unwrap() function. After that, we printed the result.

Program/Source Code:

The source code to convert a string into the float is given below. The given program is compiled and executed successfully.

// Rust program to convert a string 
// into float

fn main() 
{
    let mut strVar = "123.45";
    let mut floatVar:f32 = 0.0;
    
    floatVar=strVar.parse().unwrap();
    println!("Number is : {}",floatVar);
}

Output:

Number is : 123.45

Explanation:

Here, we created a variable strVar of &str type. Then we assigned the value of strVar variable into f32 variable using parse() and unwrap() functions. After that, we printed the result.
