Hi there,
I'm reading http://www.w3.org/TR/xpath#function-boolean for some workshop. Therein is said: >>The *boolean <http://www.w3.org/TR/xpath#function-boolean>* function converts its argument to a boolean as follows: * a number is true if and only if it is neither positive or negative
zero nor NaN<<My problem may be just lack of english language, but I need some explanation here. What is meant by positive or negative zero? From my math understandings zero is neither positive nor negative. If I drop that and say, a number is true when the value is neither zero nor NaN, would this be correct? Ciao! Kai
