title: Is there any elegant ways to convert Int to BigDecimal in Kotlin?
body: <p>I'm working on my toy project with Kotlin.</p>
  
  <p>While writing code, I feel that those codes are somewhat duplicated and not clean.</p>
  
  <pre><code>val a: Int = 1
  val a_D: BigDecimal = a.toBigDecimal()
  val b_D: BigDecimal = a.toBigDecimal()
  </code></pre>
  
  <p>So, is there any way to avoid those duplication(something like toBigDecimal()) using elegant way?     </p>
