Swift 千分位 金錢價格逗號 千分符

金錢小數點 千位符

金融商品、價格、價位..等有關於金錢的數字，通常通會用標點符號分隔，這種標點符號稱作為 千分位符號（也稱千位分隔符，group separator），譬如:10000->10,000，三位數一個逗點，讓可讀性就變高了。

寫法

let money = 1000000  // 一百萬
let formatter = NumberFormatter()
formatter.numberStyle = .decimal
formatter.maximumFractionDigits = 0
print(formatter.string(from: NSNumber(value: money))!)
// -> 1,000,000
