AssertJ comparing double values

I would like to compare double values with AssertJ. I dont catch why my test is failing.

@Test
public void testInterestToQuote() {
    double result = BasicCalculator.accumulationFactorByYearsAndInterest(years, interest)
    Assertions.assertThat(result).isCloseTo(expected, Assertions.offset(0.1d))
}

Exception is:

java.lang.AssertionError: 
Expecting:
   <7.256571590148141E-5>
to be close to:
   <7.25>
by less than <0.1> but difference was <7.249927434284099>.
(a difference of exactly <0.1> being considered valid)

Why does Assertion fail?
