Strange float serialization

Created by: anisimovsergey

I looked at FAQ and Pitfalls and couldn't find the answer. Please take a look at the following tests, I find it rather strange that OneFloatDefaultDigits3 passes successfully, does it exhibit expected behavior?

  SECTION("OneFloatDefaultDigits2") {
    array.add(0.01f);
    check(array, "[0.01]");
  }

  SECTION("OneFloatDefaultDigits3") {
    array.add(0.001f);
    check(array, "[0.00]");
  }

  SECTION("OneFloatDefaultDigits4") {
    array.add(0.0001f);
    check(array, "[10.00e-5]");
  }

I'm using Microsoft Visual Studio Enterprise 2015 Version 14.0.25123.00 Update 2
