Use AsserEquals for floating-point values
Use AsserEquals for floating-point values

Use AssertEquals for these two specific case will do a better job,
since it'll convert both '0.1' and result of `getContent()` into PHP's
internal representation of floating-point and compares them and it should be fine.
Using `AssertSame` for this tests brings floating-point serialization
into consideration which of course will be php.ini specific.

In order not missing the type assertion point that `AssertSame` does,
we also perform `assertInternalType('string'...`
