KyoDecimalNumber

A simple extension that makes it easy to manipulate NSDecimalNumber!

Features

• Simplify rounding operations in NSDecimalnumber.
• Extends the conversion of common data types to NSDecimalNumber.
• The custom operator enables + - * / > >= < <= == to be used directly on NSDecimalNumber.

Start with KyoDecimalNumber

Round

You can provide the reserved number of decimal places and specify whether the data type returned is String or NSDecimalNumber.

var price = NSDecimalNumber(string: "15.54321")
price = price.roundUp()  //NSDecimalNumber -> 15.54
var strPrice: String = price.roundUp()  //String -> 15.54
strPrice = price.roundUp(fractionNum: 1)  //String -> 15.5
let string = price.roundUp(type: String.self)  //String -> 15.54
let decimalNumber = price.roundUp(type: NSDecimalNumber.self)  //NSDecimalNumber -> 15.54

Conversion

Currently supports NSNumber String Float Double Bool Int UInt Int8 Int16 Int32 Int64 conversion to NSDecimalNumber.

let number: NSNumber = NSNumber(value: 32)
let fromNumber = number.decimalNumber()
let string: String = "32"
let fromString = string.decimalNumber()
let float: Float = 32.22
let fromFloat = float.decimalNumber()
let double: Double = 32.22
let fromDouble = double.decimalNumber()
let bool: Bool = true
let fromBool = bool.decimalNumber()
let int: Int = 32
let fromInt = int.decimalNumber()
let uint: UInt = 32
let fromUInt = uint.decimalNumber()
let int8: Int8 = 32
let fromInt8 = int8.decimalNumber()
let int16: Int16 = 32
let fromInt16 = int16.decimalNumber()
let int32: Int32 = 32
let fromInt32 = int32.decimalNumber()
let int64: Int64 = 32
let fromInt64 = int64.decimalNumber()

Custom Operator

You can use common operators on NSDecimalNumber just like value types.

var decimalNumber: NSDecimalNumber = 23.2.decimalNumber() + "15.2".decimalNumber()  //38.4
decimalNumber = nil - 15.23.decimalNumber() //-15.23
decimalNumber = decimalNumber * 2.1 //-31.983
decimalNumber = decimalNumber / "2".decimalNumber() //-15.9915
print("12".decimalNumber() >= 12) //true
print(11.decimalNumber() > 12)  //false
print(12.decimalNumber() == "12.00".decimalNumber()) //true
print(true.decimalNumber() <= "0".decimalNumber()) //false
print(100.01.decimalNumber() < 100.02) //true

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:

$ gem install cocoapods

To integrate KyoDecimalNumber into your Xcode project using CocoaPods, specify it to a target in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '11.0'
use_frameworks!

target '<Your Target Name>' do
  # your other pod
  # ...
  pod 'KyoDecimalNumber', '~> 0.0.4'
end

Manually

if you prefer not to use the aforementioned dependency managers, you can integrate KyoDecimalNumber into your project manually.

• Clone or download KyoDecimalNumber to your computer.
• Open the KyoDecimalNumber folder, and drag NSDecimalNumber+KyoOperand.swift NSDecimalNumber+KyoRoundUp.swift into the file navigator of your app project, under your app project.
• Drag NSDecimalNumber+KyoConvert.h NSDecimalNumber+KyoConvert.m to your project if you use Objective-C.
