^((10)(\.[0-0]{0,2})?$|([0-9])(\.[0-9]{1,2})?$)

the above regex code work for 0.00 to 10.00

^((0)((\.0[1-9]{1})?$|(\.[1-9][0-9]{0,2})?$)?$|(10)(\.[0-0]{0,2})?$|([1-9])(\.[0-9]{1,2})?$)
this is for 0.01 to 10.00

You may not be aware, we have been asked to allow new solutions to old posts (by Chris and Sean) - especially if they add something new, or in this case, are correct when the other two explicit solutions (1 and 3) are not

I have countered the downvote on your solution because, unlike solutions 1 and 3, your first regex handles all of the examples given and rejects the specific invalid numbers listed.
Your second regex is irrelevant and does not match the question requirements

Solution 1

Try:

^((1\d)|(\d))(\.(\d\d)|\d){0,1}$

Your regex allows numbers 11-19 also, which shouldn't be included.

Solution 3

This will work:

^(10|\d)(\.\d{1,2})?$

(10|\d) allows for a single digit or 10
(\.\d{1,2})? possible decimal followed by 1 or 2 digits
