Java - Arrays.binarySearch function equivalent in awk

Hi all

Does anyone know Java-Arrays.binarySearch function equivalent in awk
I tried like this but it's not correct one,it just returns array index if and only when searched value available in array, for some reason if searched value not found then I want to return upper nearest neighbour index. please let me know if anyone have better idea

function Arrays_binarySearch(arr,val){
                    for(b in arr){
                             return b

here is link to example in java
