【式を再利用できる電卓】
　式を確認しながら入力でき、一度計算した式を再利用できる電卓です。確認しながら入力するので誤入力や計算ミスを防ぐことができます。誤った入力をしても、クリアを押して最初からやり直す必要がありません。ディスプレイに表示されるカーソルを使って修正するこができます。また、画面の式をスクロールすると計算履歴が表示され、計算した式を修正して再計算することができます。
　ディスプレイに表示されるカーソルは、タップまたは矢印キーで編集したい場所へすばやく移動できます。また、ディスプレイをスワイプすると過去の式を見ることができます。ディスプレイのロングタップでコピー&ペーストにも対応しており、強力かつ柔軟で直感的なユーザインターフェイスを備えています。　
　計算機能は四則演算、時計計算、ルート、パーセント、税抜き、税込みの計算、メモリ、式の履歴、ラストアンスが利用できます。　
　とてもシンプルなデザインでありながら、使いやすさに重点をおいた電卓アプリです。
　
【特徴】

【主な用途】
・一般の電卓として
・営業・店舗での消費税(税抜き・税込み)や割引価格の計算
・長い式の計算
・価格や数量の計算
・家計簿の計算
・集計伝票の計算
・割り勘の計算
・経過時間の計算
・時間×時給の計算
　
【機能の解説】
・表示画面
　この電卓は長い式も複数行で表示できるので、見やすく、入力間違いを防ぐことができます。また、計算式の変更したい箇所をタップまたは矢印キーでカーソルを移動して式を簡単にすばやく修正することができます。
　
・リプレイ機能と履歴機能
　電卓画面をスクロールして計算式を編集し、改めて計算することのできるリプレイ機能を備えています。また、リプレイキー(△)を長押しすることで、計算履歴の一覧表を表示します。この表の中から式を選択して電卓画面へ表示し、数字だけを変更して再度計算することもできます。
　
・ラストアンサー機能とヒストリ機能
　一般的な電卓にはないラストアンサー機能を採用しています。直前の計算結果を記憶し、Ansキーで呼び出すことができます。また、Ansキーを長押しすることで10件までの計算結果の一覧を表示するヒストリ機能も備えています。この表から値を選択し、次の新しい計算式に活用できます。
　
・独自のC(クリア)機能
　式を誤って入力したときに値単位、演算子単位で文字を消す独自のクリア機能を採用しています。一文字だけ消したいときはBS(　例えば、100+200の後に誤って+400を入力したとします。誤って入力した400を削除するために[C]を1回押します。400が消えますので、この式の後に正しい数値を入力します。この機能により少ないキー操作ですばやく式の修正が行えます。
　
・パーセント計算機能
　「500円の20％増しはいくら？」このような計算も簡単に行えます。この電卓アプリでは「500+20%=」と入力します。この計算の答え600円を得ることができます。このパーセント計算方法は多くの電卓で採用されています。
　
【計算例】
●四則演算：
1 + 2 - 3 × 4 ÷ 5 = 0.6
　
●括弧を含む式の計算：
( 1 + 2 ) × ( 3 + 4 ) = 21
( 1 + 2 ) ( 3 + 4 ) ( 5 + 6 ) = 231
　
●平方根：
√( 2 × 2 ) = 2
　
●時間の計算
「12:45〜16:15」は何時間？
16:15-12:45=3:30:00
「時給950円で12:45〜16:15働いたときの金額は？」
950×(16:15-12:45)=3325:00:00
(続けて[時:分:秒]を押すと数値表示になります)
=3325
●パーセントの計算：
500 + 20% = 600
500 - 20% = 400
500 × 20% = 100
100 ÷ 500% = 20
　
●税込・税抜の計算： 1回の計算で税込価格、税金、税抜価格が表示されます。
500 [税込]
小計 500
消費税等(8%) 40
合計 540
　
540 [税抜]
小計 500
消費税等(8%) 40
合計 540
