ABS function implemented as a single XPath expression

Summary This snippet shows how to implement the abs() function as a single XPath expression

We need an XPath implementation of the classical abs() math function, defined as: abs(x) = x iff x >= 0 abs(x) = -x otherwise The expression is: concat( substring('-', 2 - ($pNum <0)), '1' ) * $pNum For a more general approach to conditionally generating strings within a single XPath expression, see another snippet: http://www.vbxml.com/snippetcentral/main.asp?view=viewsnippet&id=v20010328225824 Other XPath expressions implementing the abs() function have been also suggested by Bejamin Guralnik, John Ardiss, and Samuel Chen: $pNum * (translate(number(boolean(0 >= $pNum )),'10','13') - 2) ((($pNum > 0) * $pNum) + (($pNum < 0) * -$pNum)) substring('-1', 2 - ($pNum < 0)) * $pNum
