How to get the smallest possible Float in Swift

Question

I want to find, programmatically, and portably, the smallest Float possible.

By smallest I mean the smallest > 0 Float. Any way to achieve that ?

Answer 1

Looking up the documentation for Float I found: Float.leastNonzeroMagnitude

The least positive number.

This value compares less than or equal to all positive numbers, but greater than zero. If the type supports subnormal values, leastNonzeroMagnitude is smaller than leastNormalMagnitude; otherwise they are equal.
