Method Detail

assertIsNaN

public void assertIsNaN(AssertionInfo info,
                        NUMBER actual)

Verifies that the actual value is equal to NaN.
It does not rely on the custom comparisonStrategy (if one is set).

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is not equal to NaN.

absBigDecimalDiff

protected BigDecimal absBigDecimalDiff(NUMBER number1,
                                       NUMBER number2)

NaN

protected abstract NUMBER NaN()

assertIsNotNaN

public void assertIsNotNaN(AssertionInfo info,
                           NUMBER actual)

Verifies that the actual value is not equal to NaN.

Parameters:

info - contains information about the assertion.

actual - the actual value.

Throws:

AssertionError - if the actual value is equal to NaN.

isGreaterThan

protected boolean isGreaterThan(NUMBER value,
                                NUMBER other)

Specified by:

isGreaterThan in class Numbers<NUMBER extends Number & Comparable<NUMBER>>

isNanOrInfinite

public boolean isNanOrInfinite(NUMBER value)

Returns true is if the given value is Nan or Infinite, false otherwise.

Parameters:

value - the value to check

Returns:

true is if the given value is Nan or Infinite, false otherwise.

isNaN

protected abstract boolean isNaN(NUMBER value)

isNotInfinite

protected abstract boolean isNotInfinite(NUMBER value)
