# leastNormalMagnitude

The least positive normal number.

```
static var leastNormalMagnitude: Double { get }
```

## Discussion

This value compares less than or equal to all positive normal numbers.
There may be smaller positive numbers, but they are *subnormal*, meaning
that they are represented with less precision than normal numbers.

This value corresponds to type-specific C macros such as `FLT_MIN` and
`DBL_MIN`. The naming of those macros is slightly misleading, because
subnormals, zeros, and negative numbers are smaller than this value.
