It should be close to 5 times faster. With the existing code you keep subtracting the Unit Cell value until the coordinates is within range (10 to 20) separate subtractions.

The updated code uses the modulo function (%) to calculate the remainder after dividing by the Unit Cell Value. So basically it one or two division operations instead of lots of subtract or add operations.

The if-then-else operator <expr>?<true value>:<false value> deals with the border conditions (e.g. negative values wrapping to positive and edge values ending up as either zero or the Unit Cell value).

$1 is different to $2 and $3 because in your original code you have a > test for $1 and >= for $2 and $3

ADUNCORE(1)						      General Commands Manual						       ADUNCORE(1)

NAME

       AdunCore - core module of the Adun molecular simulator

SYNOPSIS

       AdunCore [OPTIONS]

DESCRIPTION

       This manual page documents briefly the AdunCore command.

       AdunCore  is  the  core	module	of  the  Adun  molecular simulator.  It is launched automatically from the UL GUI but can be used from the
       GNU/Linux console as well.  Options to AdunCore must be specified as value pairs in the form `-Option Value'.  The  following  options  are
       available:

       -Template
	      A valid Adun template.  This is the only option that is mandatory.

       -ExternalObjects
	      A  dictionary  in  plist format.	Its contents extend the externalObjects section of the template.  If there are duplicate keys this
	      dictionary takes precedence.

       -SimulationOutputDir
	      Directory where simulation data directory will be stored.  (Default value: SimulationOutput)

       -ControllerOutputDir
	      Directory where controller data will be stored.  (Default value: ControllerOutput)

       -CreateLogFiles
	      If YES log files are created.  If NO they are not.  (Default value: YES)

       -LogFile
	      File where the program output will be written.  (Default value: AdunCore.log)

       -ErrorFile
	      File where program errors and warnings will be written.  (Default value: AdunCore.errors)

       -RedirectOutput
	      If YES the log files will be moved to the simulation output directory. (Default value: YES)

       -RunInteractive
	      If YES the simulation loop is spawned as a separate thread.  The main thread then enters a run loop and can serve external requests.
	      If NO then interaction is not possible with the simulation.  (Default value: NO)

       -ConnectToAdServer
	      If  YES the simulation registers its existance with a local AdServer daemon.  This allows the simulation to be viewed and controlled
	      from the Adun GUI.  (Default value: NO)
