Method Detail

getEpsilon

public static final double getEpsilon()

Returns current epsilon value.

Returns:

Returns current epsilon value.

eq

public static final double eq(double a,
                              double b)

Equality relation.

Parameters:

a - the a number (a = b)

b - the b number (a = b)

Returns:

if a = Double.NaN or b = Double.NaN return Double.NaN, else if a = b return 1, otherwise return 0.

neq

public static final double neq(double a,
                               double b)

Inequality relation.

Parameters:

a - the a number (a <> b)

b - the b number (a <> b)

Returns:

if a = Double.NaN or b = Double.NaN return Double.NaN, else if a <> b return 1, otherwise return 0.

lt

public static final double lt(double a,
                              double b)

Lower than relation.

Parameters:

a - the a number (a < b)

b - the b number (a < b)

Returns:

if a = Double.NaN or b = Double.NaN return Double.NaN, else if a < b return 1, otherwise return 0.

gt

public static final double gt(double a,
                              double b)

Greater than relation.

Parameters:

a - the a number (a > b)

b - the b number (a > b)

Returns:

if a = Double.NaN or b = Double.NaN return Double.NaN, else if a > b return 1, otherwise return 0.

leq

public static final double leq(double a,
                               double b)

Lower or equal relation.

Parameters:

a - the a number (a <= b)

b - the b number (a <= b)

Returns:

if a = Double.NaN or b = Double.NaN return Double.NaN, else if a <= b return 1, otherwise return 0.

geq

public static final double geq(double a,
                               double b)

Greater or equal relation.

Parameters:

a - the a number (a >= b)

b - the b number (a >= b)

Returns:

if a = Double.NaN or b = Double.NaN return Double.NaN, else if a >= b return 1, otherwise return 0.
