I have an simple array:

numberarray = [6, 2, 10, 18, 11, 4, 20]
index
number = 15
result should be number_array [3]

I'm trying to return the closest number to 15. Thanks for the help!

An algorithm comparing the differences in a loop.

A very basic idea for that would be:

extends Node2D

const INT_MAX = 2147483647

func find_closest(match, array):

    var best_match = null
    var least_diff = INT_MAX

    for number in array:

        var diff = abs(match - number)

        if(diff < least_diff):
            best_match = number
            least_diff = diff

    return best_match


func _ready():

    var data = [6, 2, 10, 18, 11, 4, 20]
    print(find_closest(15, data))
