Subject: [Rd] Strange behavior of C compiled program
Message-ID: <498F5EA4.3060307@u-paris10.fr>

Hi the list,

I need to include some C code in R, but the behavior of the C code is 
strange : Here is my code :
--- 8< ---
    Rprintf("\n XXXX mTraj=%f 
mClus=%f",mTraj[i+nbId*c],mClustersCenter[j+nbClusters*c]);

    Rprintf("\nDistA=%d Tmp=%d",dist,tmp);
            tmp = mTraj[i+nbId* c] - mClustersCenter [j+nbClusters* c];

    Rprintf("\nDistB=%d Tmp=%d",dist,tmp);
            dist += (tmp * tmp);

    Rprintf("\nDistC=%d Tmp=%d",dist,tmp);
--- 8< ----

Herer are the stranges results it gives :

XXXX mTraj=1.000000 mClus=3.000000
DistA=0 Tmp=0
DistB=0 Tmp=0
DistC=0 Tmp=1074790400

I ask on a C chat, but no one can answer me.
Any idea of what wrong ?

Thanks
Christophe
