Let me give a picture to illustrate the meaning of "jump"
document.body.clientWidth*0.5) {this.resized=true;this.width=document.body.clientWidth*0.5;this.style.cursor='pointer';} else {this.onclick=null}" alt="" />
In my rough understanding, "jump" is not intergatable by Riemann Intergral, but can be integrated by Lebesgue Integral.
More comments are welcome. :)
