ROOT 6.10/09 Reference Guide |
The Base classes of ROOT.
The base classes of the ROOT system provide the core of the system. They are available to all other classes. They range from a set of abstract interfaces (TVirtualXXXXX classes), to a wide range of basic utility classes providing basic services like strings, regular expression, timers, date/time, md5 checksumming, signal/slots event handling, plugin handler, run-config resource processor, etc. etc.

TMath Base functionsDefine the functions Min, Max, Abs, Sign, Range for all types.
NB: These functions are unfortunately not available in a portable way in std::.
More functions are defined in TMath.h. TMathBase.h is designed to be a stable file and used in place of TMath.h in the ROOT miniCore. Return next prime number after x, unless x is a prime in which case x is returned.
