This question was posted in response to the following article: http://help.adobe.com/en_US/ColdFusion/10.0/CFMLRef/WSc3ff6d0ea77859461172e0811cbec22c24-7 fd9.html
Currently, under "Usage", a bullet point is "integer division (/)". However, "/" is basic arithmetic division. "\" is actually integer division. Please see: http://help.adobe.com/en_US/ColdFusion/10.0/Developing/WSc3ff6d0ea77859461172e0811cbec09d5 5-7ffc.html
So the "integer division (/)" should probably be changed to "integer division (\)".
