Double exponential

Double exponential may refer to:

• A double exponential function
  • Double exponential time, a task with time complexity roughly proportional to such a function
  • 2-EXPTIME, the complexity class of decision problems solvable in double-exponential time by a deterministic Turing machine.
• Double exponential distribution, which may refer to:
  • Laplace distribution, a bilateral exponential distribution
  • Gumbel distribution, an iterated exponential distribution
• Double exponential integration, most commonly tanh-sinh quadrature
• Double exponential smoothing
