fun FloatArray.binarySearch(element: Float, fromIndex: Int = 0, toIndex: Int = size): Int
fun FloatArray.binarySearch(element: Float, fromIndex: Int = 0, toIndex: Int = size): Int

Searches the array or the range of the array for the provided element using the binary search algorithm. The array is expected to be sorted, otherwise the result is undefined.
