# binade

The floating-point value with the same sign and exponent as this value, but with a significand of 1.0.

## Declaration

```swift
var binade: Self { get }
```

## Discussion

Discussion A binade is a set of binary floating-point values that all have the same sign and exponent. The binade property is a member of the same binade as this value, but with a unit significand. In this example, x has a value of 21.5, which is stored as 1.34375 * 2**4, where ** is exponentiation. Therefore, x.binade is equal to 1.0 * 2**4, or 16.0. let x = 21.5 // x.significand == 1.34375 // x.exponent == 4

let y = x.binade // y == 16.0 // y.significand == 1.0 // y.exponent == 4
