Please add scientific/accountant calculator

Love this keyboard, but I need scientific/accountant calculator. I would love to buy even if the functions are as in app purchases.

希望通り。

電卓アプリに切り替えるのは面倒。メモアプリ画面の中で、キーボード上で計算し入力したい。その機能を備えたキーボードがこのアプリです。メモの中で簡易的な材料代の積算が出来るようになり助かりました。出力文のカスタムなどはありませんが、アプリ容量も小さく、逆にシンプルで良かったです。感謝（*'∀'人）
