Hi, This looks like a general programming problem to me. It is always dangerous to ask for equality on real numbers. Because of a rounding problem in the calculation (because of the way computers work), the sum is not exactly equal to the number on the right hand-side. The usual algorithm to compare real numbers for equality, up to say 3 decimal numbers, is the following, comparing integers instead (replace 1000 with e.g. 100 for 2 decimal places): fn:round($n1 * 1000) = fn:round($n2 * 1000) Regards, -- Florent Georges http://fgeorges.org/ http://h2oconsulting.be/ On 12 March 2015 at 15:01, ankit kumar <anky4bugs@gmail.com> wrote:

Hi,

I am trying to evaluate this expression, it is supposed to give TRUE but, it is giving false.

sum((<a>5923.17</a>,<a>5956.29</a>,<a>5989.28</a>)) = <a>17868.74</a>

But, for this expression it is giving as expected.

sum((<a>5922.78</a>,<a>-5955.78</a>,<a>5988.74</a>)) = <a>5955.74</a>

Thanks
