percent — (%) 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 SCIDIR/macros/percent
.
