法律研究Kotlin 程式計算複利
在本文中，我們將瞭解如何計算複利。複利是指對本金和累計利息收取的百分比利息。與單利相比，利率更高。複利的計算公式如下
principle * (Math.pow((1 + rate / 100), time)) – principle
下面是相同的演示
假設我們的輸入是
Principle number: 100000 Interest rate: 5 Time period in years: 3
期望的輸出將是 -
The Compound Interest is: 15762.50000000001
演算法
步驟 1 - 開始
步驟 2 - 宣告四個整數值 principalAmount、interestRate、timePeriod、compoundInterest
步驟 3 - 定義 principalAmount、interestRate、timePeriod、compoundInterest 的值。
步驟 4 - 執行 “principle * (Math.pow((1 + rate / 100), time)) – principle” 計算複利並將其儲存在 compoundInterest 變數中
步驟 5 - 顯示 compoundInterest
步驟 6 - 停止
示例 1
在此示例中，我們將使用上述公式在 Kotlin 中計算複利。首先，宣告並設定本金變數 -
val principalAmount = 10000
然後，設定利率和期限變數 -
val interestRate = 5 val timePeriod = 3
現在，使用上述公式計算複利
val compoundInterest = principalAmount.toDouble() * Math.pow((1 + interestRate.toDouble()/100.00),timePeriod.toDouble())- principalAmount
讓我們看看在 Kotlin 中計算複利的示例 -
fun main() { val principalAmount = 10000 println("Principal amount is defined as: $principalAmount") val interestRate = 5 println("The rate of interest is defined as: $interestRate %") val timePeriod = 3 println("The time period is defined as: $timePeriod years") val compoundInterest = principalAmount.toDouble() * Math.pow((1 + interestRate.toDouble()/100.00),timePeriod.toDouble())- principalAmount println("
Compound Interest is: $compoundInterest") }
輸出
Principal amount is defined as: 10000 The rate of interest is defined as: 5 % The time period is defined as: 3 years Compound Interest is: 1576.250000000002
示例 2
在此示例中，我們將計算 Kotlin 中的複利
fun main() { val principalAmount = 10000 println("Principal amount is defined as: $principalAmount") val interestRate = 5 println("The rate of interest is defined as: $interestRate %") val timePeriod = 3 println("The time period is defined as: $timePeriod years") getCompoundInterest(principalAmount, interestRate, timePeriod) } fun getCompoundInterest(principalAmount: Int, interestRate: Int, timePeriod: Int) { val compoundInterest = principalAmount.toDouble() * Math.pow((1 + interestRate.toDouble()/100.00),timePeriod.toDouble()) - principalAmount println("
Compound Interest is: $compoundInterest") }
輸出
Principal amount is defined as: 10000 The rate of interest is defined as: 5 % The time period is defined as: 3 years Compound Interest is: 1576.250000000002
