How to Declare a Float Array in Kotlin ?

Answer

To declare a float array in Kotlin, you can use the floatArrayOf function or initialize an array of floats.

✐ Examples

1 Declare a Float Array using floatArrayOf Function

In this example,

We use the floatArrayOf function to declare a float array named floatArray with specific float values.
The floatArrayOf function takes float values as arguments and creates an array with those values.
Finally, we print the float array to standard output.

Kotlin Program

fun main(args: Array<String>) {
    val floatArray = floatArrayOf(1.1f, 2.2f, 3.3f, 4.4f, 5.5f)
    println("Float array: ${floatArray.joinToString()}")
}

Output

Float array: 1.1, 2.2, 3.3, 4.4, 5.5

2 Declare a Float Array using Array Initialization

In this example,

We declare a float array named floatArray using the FloatArray constructor with the desired size.
We assign float values to each element of the array using array indexing.
Finally, we print the float array to standard output.

Kotlin Program

fun main(args: Array<String>) {
    val floatArray = FloatArray(5)
    floatArray[0] = 1.1f
    floatArray[1] = 2.2f
    floatArray[2] = 3.3f
    floatArray[3] = 4.4f
    floatArray[4] = 5.5f
    println("Float array: ${floatArray.joinToString()}")
}

Output

Float array: 1.1, 2.2, 3.3, 4.4, 5.5
