Re: [Exist-development] [exist:code] dizzzz committed to eXist-db Code: [ignore] introduction of function namespace "http://www.w3.org/2005/xpath-functions/math" of xquery3/xpath3 (see http://www.w3.org/TR/xpath-functions-30/#trigonometry). Basically it is a copy/stripdown from the already existing eXist-db math extension I wrote ages ago; the latter will be stripped so there will be no functions doubled. WorkInProgress.

Is there by chance a workaround to this error I am getting? I tried using
"mathext" as the namespace as suggested previously, but the nature of the
error did not change at all:

Function math:abs() is not defined in module namespace:
http://www.w3.org/2005/xpath-functions/math

Other math functions I have dependencies on are math:ceil, math:floor, and
math:power.

I tried referring to the documentation but I'm also having difficulties
getting the dashboard to work properly today. ;)
