Regex to check amount is greator then one

I have a regex

^(?=.*[1-9])\\d{0,5}(?:\\.\\d{0,2})?$

to check amount should be greater then 0 and it can contain maximum five digit before decimal and optional decimal and 2 digits after decimal. Here (?=.*[1-9]) is to check there should be latest one occurrence of any digit from (1-9) in the string.

But I want modify it to check amount greater then one(1), so I want (?=.*[1-9]) to check only till the occurrence of the decimal point i.e. 0.1 it should return false. Other condition should also fulfill.

Note : the count of digits before decimal is not fix, it will very from 1 to 5, so we can't modify it to (?=.{0,5}[1-9])

You can fix it by using this negation based regex:

^(?=[^.]*[1-9])\\d{0,5}(?:\\.\\d{0,2})?$

RegEx Demo

[^.]* before [1-9] will match any character except decimal point thus not allowing 0.45 as valid number.
