closeTo

public static Matcher<BigDecimal> closeTo(BigDecimal operand,
                                          BigDecimal error)

Creates a matcher of BigDecimals that matches when an examined BigDecimal is equal to the specified operand, within a range of +/- error. The comparison for equality is done by BigDecimals BigDecimal.compareTo(java.math.BigDecimal) method.

For example:

assertThat(new BigDecimal("1.03"), is(closeTo(new BigDecimal("1.0"), new BigDecimal("0.03"))))

Parameters:

operand - the expected value of matching BigDecimals

error - the delta (+/-) within which matches will be allowed
