in reply to fastest way to compare numerical strings?

Just a quick note:

The take the abs value of the difference between the 2 numbers, check if that is greater than .01. That should read cleaner and get rid of most of those checks.

Also as a favor for the people trying to read your code - pick a style of indenting.

#untested for ($n=0;$n<=$#lat;$n++) { for ($v=0;$v<=$#lat;$v++) { if ( abs( $lat[$n] - $lat[$v] ) < .01 and abs( $long[$n] - $l +ong[$v] ) < .01 ) { ##OTHER CODE } } }
Update: fixed typo and minor edit
One dead unjugged rabbit fish later...
