SHBinarySearchForRange

A simple library to perform binary search to find the nearest double/float value from a double/float array for a given double/float.

Overview

This cocoapod helps to find the nearest ceiling double/float value from a double/float array by performing a binary search operation.

Requirements

• ARC
• iOS8

Installation

SHBinarySearchForRange is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "SHBinarySearchForRange"

Usage

``` #import "SHBinarySearchForRange.h"

NSArray *array = @[@0.12f, @0.23f, @0.3f, @0.345f, @0.967f, @1.0f];

SHBinarySearchForRange *binarySearch = [[SHBinarySearchForRange alloc] initWithValues:array];

NSInteger index = [binarySearch indexOfClosestCeilingForSearchItem:10.67575f];

NSNumber *valAtIndex = [array objectAtIndex:index];

NSLog(@"Value close to range: %f", valAtIndex.doubleValue); ```
