(%) special character


Some predefined variables names begin with %, such as %i (for sqrt(-1)), %inf (for Infinity), %pi (for 3.14...), %T (for the boolean constant "true"),...

In addition, functions whose names begin with % are special : they are used for primitives and operators overloading (see overloading).

For example the function %rmr performs the multiplication (m) operation x*y for x and y rational matrices (r). The coding conventions are given by the readme file in directory SCI/modules/overloading/macros.
