This group, denoted , is defined as the group (under composition) of functions of the form:
Equivalently, it can be defined as the external semidirect product where the latter is the multiplicative group of positive reals and it act on the former by multiplication.
Note that, via the logarithm map, the acting group is isomorphic to . Thus, the group can be defined as where (as an element of the acting group) acts on (as an element of the base group) by .
