    • value

      public static double value(double x)
      Returns the inverse error function.

      Special cases:

      • If the argument is 0, then the result is 0.
      • If the argument is 1, then the result is positive infinity.
      • If the argument is -1, then the result is negative infinity.
      • If the argument is outside the interval [-1, 1], then the result is nan.
      • If the argument is nan, then the result is nan.

      x - Value (in [-1, 1])
      Returns:
      t such that x = Erf.value(t).
