How to fix warning (trailing zeros added)

[dtowell]

I got the following warning:
No validator rejects trailing zeros added to real number decimal portion

I am using CTD to validate:
FLOAT(0,10^9)

It feels like this should be fine, and I don't know what the recommended method to "fix" the warning. I could change to REGEX() but that begs the question as to the value of FLOAT().

Any hints would be appreciated.

I recommend using the CTD feature FLOATP rather than FLOAT, because FLOATP allows you to specify the maximum number of digits after the decimal point. It's generally a good idea (IMO) to specify the maximum precision for a problem (and give this information in the problem as well). See for example the input specification for https://open.kattis.com/problems/dartscoring

Thank you. That is great.
