There seems to be a bug in the Ttree::Scan() member function in root 2.012
at least under DEC OSF1
Scanning a tree for the event ID variable Idev, I get with root 2.011
the correct output:
root [4] h1.Scan("Idev")
************************
* Row * Idev *
************************
* 0 * 1 *
* 1 * -2 *
* 2 * -3 *
* 3 * 4 *
* 4 * 5 *
* 5 * 6 *
* 6 * 7 *
* 7 * 8 *
* 8 * 9 *
* 9 * 10 *
* 10 * 11 *
* 11 * 12 *
* 12 * 13 *
* 13 * -14 *
* 14 * 15 *
but with version 2.012 I get wrong representation of negative values:
root [4] h1.Scan("Idev")
************************
* Row * Idev *
************************
* 0 * 1 *
* 1 * 4.295e+09 *
* 2 * 4.295e+09 *
* 3 * 4 *
* 4 * 5 *
* 5 * 6 *
* 6 * 7 *
* 7 * 8 *
* 8 * 9 *
* 9 * 10 *
* 10 * 11 *
* 11 * 12 *
* 12 * 13 *
* 13 * 4.295e+09 *
* 14 * 15 *
