### Question:
SpecialMath { public static double getMachineEpsilon() { if (machineEpsilon == 0.0) { machineEpsilon = 0.5; while (1+machineEpsilon > 1) machineEpsilon /= 2; } return machineEpsilon; }  static double getMachineEpsilon(); static double evaluatePolynomial(double x, double[] coefficients); static double calculateCompleteEllipticIntegralOfTheFirstKind(double m); static double[] calculateJacobianEllipticFunctionsValues(double u, double m); static int factorial(int n); static int combinations(int n, int k); static double complement(double angle); static double[] unwrap(double[] angles); static boolean isOdd(int x); static boolean isEven(int x); static double acosh(final double a); static double asinh(double a);  }### Answer:
@Test public void testGetMachineEpsilon() { assertEquals(1.1102230246251565E-16, getMachineEpsilon(), 1e-32); }
