<![CDATA[Get(true).proportion returns NaN]]>The metadata script:

return WTenabled.past(HOUR, 1).get(true).proportion * 100; // % on last hour

works in Mango 1.12.3, returning values between 0 and 100 inclusive depending on the past hour.

However, it no longer works in MA 2.0: it returns: "Success. result=NaN"
If I change get(true) to get(false):

return WTenabled.past(HOUR, 1).get(false).proportion * 100; // % on last hour

it returns: "Success. result=0.0"
I wonder if the proportion code is missing a check for 0/0?

Would that be 2.0.4? Where can I find the release notes or planned release date?

Also, get(false).proportion returns 0.0 but get(true).proportion returns NaN. If false returns 0.0, shouldn't true return 1.0?

I see that now there is a .percentage function that can be used insead of .proportion * 100%. I tried it with the same result.

Thank you for helping.

You may need to add a check for "count > 0". (Not the actual code required, just saying...)
