NCL uses a operator, % , to perform the "mod" function.
One caveat, this works with variables of type integer, short and byte.
If n and m are (say) integers,
k = n%m

--- You can write your own MOD function that behaves like the the fortran mod function. A simple version would be: undef ("MOD") function MOD (r1:numeric, r2:numeric) begin if (typeof(r1).eq."float" .and. typeof(r2).eq."float") then return( r1 - (r2 * floattointeger(r1 / r2)) ) end if if (typeof(r1).eq."double" .or. typeof(r2).eq."double") then return( r1 - (r2 * doubletointeger(r1 / r2)) ) ; be careful mixing types end if return( r1 % r2 ) ; type must be integer, short, byte end _______________________________________________ ncl-talk mailing list ncl-talk_at_ucar.edu http://mailman.ucar.edu/mailman/listinfo/ncl-talkReceived on Sat Oct 07 2006 - 11:22:41 MDT
