	<title>함수</title>
    
    <p>함수 이름과 함수 인자를 입력하는 방식으로 함수를 사용할 수 있습니다. <app>계산기</app> 에서는 사용자 정의 함수도 지원합니다. 인자가 숫자 값이 아니거나 <link xref="variable">단일 변수</link>일 경우, 각 인자를 세미콜론으로 구분하여 작성하시고, 인자 목록을 괄호로 감싸십시오.</p>
    <example>
    <p its:locNote="Translators: Do not translate the word 'sin'!">sin 30</p>
    <p its:locNote="Translators: Do not translate the word 'abs'!">abs (5−9)</p>
    <p its:locNote="Translators: Do not translate the word 'fun'!">fun (9;10)</p>
    </example>
    <p>
    To add a new function type the function in the format as given below. A function name and arguments must only contain upper or lower case characters, or underscores. The part after @ is the function description which is optional.
    </p>
    <example>
    <p>SimpleInterest (principal; rate; time) = principal * rate * time @ Simple Interest formula</p>
    </example>
    <p>f(x) 단추로 함수를 추가하고 입력할 수 있습니다.</p>
    <example>
    <p>f(x)를 누르십시오. 상자에 함수 이름을 입력하시고 인자 값으로 쓸 숫자를 입력한 다음 더하기 기호를 눌러 계산을 진행하십시오. 계산기 화면에 함수 수식을 입력하고 <key>Enter</key>키를 입력하십시오.</p>
    </example>
    <example>
    <p>f(x)를 누르십시오. 함수를 선택하고 해당 함수를 누르십시오.</p>
    </example>
    <p>다음 함수가 정의되어 있습니다.</p>
