nextUp

The least representable value that compares greater than this value.

Declaration

var nextUp: Float16 { get }

Discussion

For any finite value x, x.nextUp is greater than x. For nan or infinity, x.nextUp is x itself. The following special cases also apply:

  • If x is -infinity, then x.nextUp is -greatestFiniteMagnitude.

  • If x is -leastNonzeroMagnitude, then x.nextUp is -0.0.

  • If x is zero, then x.nextUp is leastNonzeroMagnitude.

  • If x is greatestFiniteMagnitude, then x.nextUp is infinity.
