# greatestFiniteMagnitude

The greatest finite number representable by this type.

## Declaration

```swift
static var greatestFiniteMagnitude: Float80 { get }
```

## Discussion

Discussion This value compares greater than or equal to all finite numbers, but less than infinity. This value corresponds to type-specific C macros such as FLT_MAX and DBL_MAX. The naming of those macros is slightly misleading, because infinity is greater than this value.
