How to Declare a Float Array in Rust

How to Declare a Float Array in Rust ?

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

In this example,

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

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

Float Array: [1.2, 3.4, 5.6]

In this example,

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

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

Empty Float Array: []
