I have a question, if I have to assert a double value of 1.0, then I have to use isEqualTo(1.0) to assert the value. But if I have to assert the value of 1.0e-6, then I have to use isEqualTo(1.0e-6) to assert the value. I am not able to understand why we have to use isEqualTo(1.0) to assert the value of 1.0 and why we have to use isEqualTo(1.0e-6) to assert the value of 1.0e-6. I am not able to understand the logic behind it. Can anybody help me to understand the logic behind it?
