I recommend test coverage for the following cases (apologies if they are already covered but I didn't see them):
- trim, eg,
". 0.123" - Multiple leading zeros:
"000.123" - Multiple trailing zeros:
"12.234000" - empty string
"" - whitespace string
" " - Invalid
"4.4.5"

Thanks. Added more test coverage including these cases and Nulls.

I recommend a test for an input array that has Nulls in it as well
