# isMathSymbol

A Boolean value indicating whether this character represents a symbol
that naturally appears in mathematical contexts.

```
var isMathSymbol: Bool { get }
```

## Discussion

For example, the following characters all represent math symbols:

- “+” (U+002B PLUS SIGN)
- “∫” (U+222B INTEGRAL)
- “ϰ” (U+03F0 GREEK KAPPA SYMBOL)

The set of characters that have an `isMathSymbol` value of `true` is not
a strict subset of those for which `isSymbol` is `true`. This includes
characters used both as letters and commonly in mathematical formulas.
For example, “ϰ” (U+03F0 GREEK KAPPA SYMBOL) is considered both a
mathematical symbol and a letter.

This property corresponds to the “Math” property in the
[Unicode Standard](http://www.unicode.org/versions/latest/).
