Fixed issue with ordinal numbers

[hbugdoll]

What are you changing/introducing

Ordinal numbers of the form cardinal number followed by point, e.g. "24.", are not detected as floats by StringHelper::isFloat() any longer.
And so they are not casted to integers by StringHelper::typeCastNumeric().

What is the reason for changing/introducing

see issue #18

The tests seems to fail:

1. we need a new tests for your changeset
2. we have to decide if we can change the unit test, but this is considered as breaking change.

The tests seems to fail:

Sorry, my fault.
I forgot the PHP regex delimiters ^ and $, tests passed now.

1. we need a new tests for your changeset
2. we have to decide if we can change the unit test, but this is considered as breaking change.

I've added two new assertions to StringHelperTest::testIsFloat()

• '.5' → true
• '5.' → false

and two new ones to StringHelperTest::testTypeCastNumeric()

• '.5' → 0.5
• '5.' → '5.'.

Or would it be better to put them into a new separate test StringHelperTest::testOrdinalNumber() regarding backwards compatibility?

Its perfect, thanks. Since you have not changed an existing tests, this looks good to me 👍
