How to get a match using regex to truncate zeroes in a string like this
45.9390 => 45.939
32.00 => 32.0 [Need this for my use case]
32.0050 => 32.005
32 => 32
I am using Java. I am just looking for the regex. This is my closest attempt( https://regex101.com/r/mD7gK4/79 ). I am missing on the second case.

I have edited your regex:
^([+-]?\d*\.0)0+$|^([+-]?\d*\.?\d*?)0*$
and use \1\2
as substitution string:
Demo: https://regex101.com/r/mD7gK4/81
Output:
45.9390 => 45.939
32.00 => 32.0
32.0050 => 32.005
32 => 32
