Calculating distance between two points


function getDistance(x0,y0,x1,y1)
{
var dx=x1-x0;
var dy=y1-y0;
var sqr=Math.pow(dx,2)+Math.pow(dy,2);
return (Math.sqrt(sqr));
}
var a=15,b=26,c=18,d=30;
trace("The distance between ("+a+","+b+") and ("+c+","+d+")     points        is:"+getDistance(a,b,c,d)); 


---------------------------------------------------------------------------------
output
-------------------------------------------------------------------------------
The distance between (15,26) and (18,30) points is:5
