I'm aiming to remove a succeeding occurrence of 2 particular characters from a string: the dot and the negative sign. let's say we have `-123-456.78.9.0-12`, I should be getting `-123456.789012` afterwards. can it be done via regex replace?

If I may add, my complete goal is to just allow numbers, negative sign, and dot, with the negative sign only being allowed either as the first character or not present at all.

thanks so much
