How to Declare a Float Array in Rust - Step by Step Examples



How to Declare a Float Array in Rust ?

Answer

To declare a float array in Rust, you can use array notation or the Vec type.



✐ Examples

1 Declare and Initialize a Float Array

In this example,

  1. We declare a float array named floatArray with predefined values using array notation.
  2. We print the array elements to the console to demonstrate the initialization.

Rust Program

fn main() {
    let float_array: [f32; 3] = [1.2, 3.4, 5.6];
    println!("Float Array: {:?}", float_array);
}

Output

Float Array: [1.2, 3.4, 5.6]

2 Declare an Empty Float Array

In this example,

  1. We declare an empty float array named empty_float_array using the Vec type without any elements.
  2. We print the array elements to the console to demonstrate the declaration.

Rust Program

fn main() {
    let empty_float_array: Vec<f32> = Vec::new();
    println!("Empty Float Array: {:?}", empty_float_array);
}

Output

Empty Float Array: []

In this tutorial, we learned How to Declare a Float Array in Rust language with well detailed examples.
