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.

Ah, got it. I'm still processing my first cup of coffee this morning. This
worked for all function calls except for the following error I get. I've
tried the math and math-ext namespaces, but the power() function doesn't
exist in either

Function math-ext:power() is not defined in module namespace:
