# isMathSymbol

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

## Declaration

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

## Discussion

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.
