Field Detail

EXACT

static final FloatingPointTolerance EXACT

A tolerance requiring exact value equivalence.

Method Detail

isWithinTolerance

boolean isWithinTolerance(float value1,
                          float value2)

Indicates whether the specified values are equal under the tolerance.

Parameters:

value1 - the first value to compare

value2 - the second value to compare

Returns:

true if the two values lie with the error bounds, otherwise false

isWithinTolerance

boolean isWithinTolerance(double value1,
                          double value2)

Indicates whether the specified values are equal under the tolerance.

Parameters:

value1 - the first value to compare

value2 - the second value to compare

Returns:

true if the two values lie with the error bounds, otherwise false

isWithinTolerance

boolean isWithinTolerance(BigDecimal value1,
                          BigDecimal value2)

Indicates whether the specified values are equal under the tolerance.

Parameters:

value1 - the first value to compare

value2 - the second value to compare

Returns:

true if the two values lie with the error bounds, otherwise false
