It is possible to load formulas made on external devices such as computers.

(Creating formula files)

Create the formula in a text editor application. The format should be as below.

Formula name 1;Formula 1

Formula name 2;Formula 2

Formula name 3;Formula 3

Warning:

Enter the formula name, followed by a semi colon and then the formula itself. Enter the next formula on a new line. The app will automatically recognize the formulas being on different lines.

Please use UTF-8 text.

You can use Chinese characters in the formula name.

For the formula, you can use only letters, numbers, brackets (), mathematical signs × * ÷ / + - ^ % ! and fixed numbers π е.

For √(), sqrt() and for ∛(), cbrt() can also be used.

File name is optional.

(Example of a formula file)

Area of a circle;S=π÷4×D^2

Circumference of a circle;L=π×D

Volume of a sphere;V=π÷6×D^3

(About special characters)

Special characters other than ASCII may be used. But be careful, as only the base natural logarithm e can be used. Letters other than е will be rendered as regular letters.

Multiplication ×：code U+00D7　

Division ÷：code U+00F7

Roots √：code U+221A

Cube root  ∛：code U+221B

Ratio of circumference of a circle to its diameter π：U+03C0（Greek π)
Base natural logarithm е：U+0435 (For convenience, the cyrillic letter e is used)
