Do you want to try Numi 3 Beta? It now supports unit conversion and has some neat features you will definetely like! Free download on the front page.

If your text contains a numeric expression that you do not want to use in the calculation, use quotation marks (”...” or '...'). The content between quotes shall not be computed. Similarly, you can use the division of the text by a colon (:) all text before the colon will be neglected.

Your operations will be calculated according to the correct mathematical order. So, if you entered 100+100/100 the result will be 101, and not 2, since division has precedence over addition. Parentheses can be used instead, in order to discern order of operations , for example: (100+100)/100, which will trigger the result of 2.

The program uses the point as decimal separator, as shown in the system settings. You can check this option in the System Settings.

The first version of Numi delineates the input of a title and an expression. With version 2, you can say goodbye to such a limitation. If you still want to use titles with numbers, simply use quotation marks or a colon, as described above.

Numeric expressions might have a suffix that will be displayed with a smaller font size. To use this feature, the suffix must immediately follow the number (without spaces).

```
20things × $100
```

Numi uses regular operation keys and formats them accordingly. So, for example, you will use '/' for division, and it will be automatically formatted as '÷' in Numi. The same rule applies for multiplication: you will use the '*' sign, and this will be formatted as '×' in Numi. The multiplication sign is very similar to the 'x' from your keyboard, but using the x letter will mean to Numi just regular text.

Some fonts do not inherently contain glyphs for mathematical symbols. In this case, instead of multiplying or dividing signs, you will see random characters, or even blank signs.

In order to fine-tune the precision of your results, go to Preferences and enter the number of digits to be displayed after the decimal point.

When you click on a result, the value will be instantly copied to the clipboard. When you copy text, for selected rows the result will be copied, as well.

To declare variables use the equal sign (=). Using variables in calculations is allowed only after they are declared (i.e., below declaration).

```
Price = $100
Total = price + 18% tax
```

In order to use both text and variables, use quotation marks or colon. The variable names are not case-sensitive. To declare multiple variables on the same line, use a semicolon as a delimiter.

Arithmetic operations:

- + — Addition
- - — Subtraction
- × — Multiplication
- ÷ — Division
- ^ — Exponentiation
- sqrt — Square root

Trigonometric functions. Argument by default in radians:

- sin — Sinus
- cos — Cosine
- tg — Tangent

To use argument in degrees, use the sign ° as suffix (Alt + Shift + 8 on Mac OS, Alt+248 on Windows). For example:

```
sin30°
sin(30)°
not sin(30°)
```

Other operations and constants:

- total — Calculates the sum of all the lines above, up to the first empty one.
- pi — Constant π

To calculate 100% of a value, if only part of it is known, divide by the percentage:

```
25÷10% → 250 25 — is 10% of the value.
```

To calculate a percentage of a value, multiply by a percentage:

```
25×10% → 2,5 Find 10% of 25.
```
