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.

[Dannes W. <da...@ex...>]

it should read math-ext:abs() ;

note that the w3c/math namespace does not contain the abs() function ......
that is why I retained the math-ext: namespace :-)

anyway, i'll bring the original functions back again, mark them deprecated,
to have them removed in 2.1/2.2/....

cheers

Dannes
