# sign

The sign of the floating-point value.

## Declaration

```swift
var sign: FloatingPointSign { get }
```

## Discussion

Discussion The sign property is .minus if the value’s signbit is set, and .plus otherwise. For example: let x = -33.375 // x.sign == .minus Don’t use this property to check whether a floating point value is negative. For a value x, the comparison x.sign == .minus is not necessarily the same as x < 0. In particular, x.sign == .minus if x is -0, and while x < 0 is always false if x is NaN, x.sign could be either .plus or .minus.
