4.5.4.2 Arithmetic Expressions.
A parameter value can also be defined by an arithmetic expression consisting of integer and
decimal constants, other variables, arithmetic operators and the brackets "(" and ")". The
standard arithmetic precedence rules apply. The following arithmetic operators are available:
Example
%AMRect*
21,1,$1,$2-2x$3,-$4,-$5+$2,0*%
The corresponding AD command could be:
%ADD146Rect,0.0807087X0.1023622X0.0118110X0.5000000X0.3000000*%
