Regex greater than zero with 2 decimal places
The code below allows both ,
and .
.
^(?=.*[1-9])[0-9]*[.,]?[0-9]{1,2}$
/^[0-9]*(\.{1})?([0-91-9][1-9])?$/
try this it passes all your cases
How about this:
^\s*(?=.*[1-9])\d*(?:\.\d{1,2})?\s*$
Explanation:
^ # Start of string
\s* # Optional whitespace
(?=.*[1-9]) # Assert that at least one digit > 0 is present in the string
\d* # integer part (optional)
(?: # decimal part:
\. # dot
\d{1,2} # plus one or two decimal digits
)? # (optional)
\s* # Optional whitespace
$ # End of string
Test in Python:
>>> import re
>>> test = [".1", "0.1", "1.12", "123.12", "92", "092", "092.13", "0", "0.0", "0.00", "00", "1.234", "-1", "-1.2"]
>>> r = re.compile(r"^\s*(?=.*[1-9])\d*(?:\.\d{1,2})?\s*$")
>>> for item in test:
... print(item, "matches" if r.match(item) else "doesn't match")
...
