Method Detail

equals

public static boolean equals(double a,
                             double b)

Returns true if two doubles are considered equal. Tests if the absolute difference between two doubles has a difference less then EPSILON.

Parameters:

a - double to compare.

b - double to compare.

Returns:

true true if two doubles are considered equal.

equals

public static boolean equals(double a,
                             double b,
                             double epsilon)

Returns true if two doubles are considered equal. Tests if the absolute difference between the two doubles has a difference less then a given double (epsilon).

Parameters:

a - double to compare.

b - double to compare

epsilon - double which is compared to the absolute difference of two doubles to determine if they are equal.

Returns:

true if a is considered equal to b.

greaterThan

public static boolean greaterThan(double a,
                                  double b)

Returns true if the first double is considered greater than the second double. Test if the difference of first minus second is greater then .EPSILON.

Parameters:

a - first double

b - second double

Returns:

true if the first double is considered greater than the second double

greaterThan

public static boolean greaterThan(double a,
                                  double b,
                                  double epsilon)

Returns true if the first double is considered greater than the second double. Test if the difference of first minus second is greater then a given double (epsilon).

Parameters:

a - first double

b - second double

Returns:

true if the first double is considered greater than the second double

lessThan

public static boolean lessThan(double a,
                               double b)

Returns true if the first double is considered less than the second double. Test if the difference of second minus first is greater then EPSILON.

Parameters:

a - first double

b - second double

Returns:

true if the first double is considered less than the second double

lessThan

public static boolean lessThan(double a,
                               double b,
                               double epsilon)

Returns true if the first double is considered less than the second double. Test if the difference of second minus first is greater then a given double (epsilon).

Parameters:

a - first double

b - second double

Returns:

true if the first double is considered less than the second double

lessOrEqual

greaterOrEqual

public static boolean greaterOrEqual(double a,
                                     double b)

greaterOrEqual

public static boolean greaterOrEqual(double a,
                                     double b,
                                     double epsilon)
