Method Summary

Modifier and Type	Method	Description
void	assertEqual(AssertionInfo info, java.lang.Double actual, java.lang.Double expected, Offset<java.lang.Double> offset)	Verifies that two floats are equal within a positive offset. It does not rely on the custom comparisonStrategy (if one is set) because using an offset is already a specific comparison strategy.
static Doubles	instance()	Returns the singleton instance of this class based on StandardComparisonStrategy.
protected boolean	isEqualTo(java.lang.Double actual, java.lang.Double expected, Offset<?> offset)	Returns true if the two floats parameter are equal within a positive offset, false otherwise. It does not rely on the custom comparisonStrategy (if one is set) because using an offset is already a specific comparison strategy.
protected java.lang.Double	NaN()
protected java.lang.Double	zero()

Method Detail

instance

public static Doubles instance()

Returns the singleton instance of this class based on StandardComparisonStrategy.

Returns:

the singleton instance of this class based on StandardComparisonStrategy.

zero

protected java.lang.Double zero()

Specified by:

zero in class Numbers<java.lang.Double>

NaN

protected java.lang.Double NaN()

Specified by:

NaN in class RealNumbers<java.lang.Double>

assertEqual

public void assertEqual(AssertionInfo info,
                        java.lang.Double actual,
                        java.lang.Double expected,
                        Offset<java.lang.Double> offset)

Verifies that two floats are equal within a positive offset.
It does not rely on the custom comparisonStrategy (if one is set) because using an offset is already a specific comparison strategy.

Parameters:

info - contains information about the assertion.

actual - the actual value.

expected - the expected value.

offset - the given positive offset.

Throws:

java.lang.NullPointerException - if the given offset is null.

java.lang.AssertionError - if the actual value is null.

java.lang.AssertionError - if the actual value is not equal to the expected one.

isEqualTo

protected boolean isEqualTo(java.lang.Double actual,
                            java.lang.Double expected,
                            Offset<?> offset)

Description copied from class: RealNumbers

Returns true if the two floats parameter are equal within a positive offset, false otherwise.
It does not rely on the custom comparisonStrategy (if one is set) because using an offset is already a specific comparison strategy.

Specified by:

isEqualTo in class RealNumbers<java.lang.Double>

Parameters:

actual - the actual value.

expected - the expected value.

offset - the given positive offset.

Returns:

true if the two floats parameter are equal within a positive offset, false otherwise.
