  The precision frontier in collider physics is being pushed at impressive
speed, from both the experimental and the theoretical side. The aim of this
review is to give an overview of recent developments in precision calculations
within the Standard Model of particle physics, in particular in the Higgs
sector. While the first part focuses on phenomenological results, the second
part reviews some of the techniques which allowed the rapid progress in the
field of precision calculations. The focus is on analytic and semi-numerical
techniques for multi-loop amplitudes, however fully numerical methods as well
as subtraction schemes for infrared divergent real radiation beyond NLO are
also briefly described.
