The equation parser-evaluator for COMPLEX number math expressions with parse-tree builder and user-friendly interface for parsing and evaluation a run-time defined math complex number expression. The math expressions is represented as string in a function style F(x1, x2,..., xn) =f(x1, x2,..., xn) , where F(x1, x2,..., xn) - declares number and names of the variables; f(x1, x2,..., xn) - math expression may contain:

Easy Math Solution has developed and implemented GDSIIExporter. GDSIIExporter helps to programmers to create the GDSII stream format file for transferring or archiving 2D graphical design data. The format is most commonly used format for electron beam lithography, photo mask production and optical circuit design.
