[10.x] Fixing number helper for floating 0.0 (#49277)

* added test case for 0.0 and 0.00 in Number helper

* added int type casting while checking for 0

I have added tests which are failing if we pass 0.0 or 0.00 floating value for 0 giving Division by zero exception...

* Fix comparison of float values in summarize method

* Refactor number formatting and summarization

* Fix formatting in SupportNumberTest.php

* Refactor SupportNumberTest abbreviate method
