[Gate-users] More than One Alias error and simple arithmetic in GATE

[Gergely Patay]

Hi,

basic arithmetic expressions ("add", "subtract", "multiply", "divide", 
"remainder") are available in Geant macros, under the command directory /control 
. They are easy to use if you get used to the quite assembly-ish syntax.

E.g. this is a valid macro excerpt:

/control/alias radius 40.0
/control/alias crystallength 10.0
/control/divide temp {crystallength} 2.0
/control/add effectiveradius {radius} {temp}
# the {effectiveradius} will now hold the value 45.0

The full documentation is avaliable here:
http://geant4.web.cern.ch/geant4/UserDocumentation/UsersGuides/ForApplicationDeveloper/html/AllResources/Control/UIcommands/_control_.html

best regards,

  Gergely
