Verifies that two floats are equal within a positive offset.<br>
It does not rely on the custom comparisionStrategy (if one is set) because using an offset is already a specific
comparison strategy.

@param description describes the information about the assertion.
@param actual the <em>actual</em> value.
@param expected the <em>expected</em> value.
@param offset the given positive <em>offset</em>.
@throws NullPointerException if the given <em>offset</em> is {@code null}.
@throws AssertionError if the <em>actual</em> value is {@code null}.
@throws AssertionError if the <em>actual</em> value is not equal to the <em>expected</em> one.
