i also made 1 but mine is little more advance im an medium DOS programmer, but my only single problem to my calculator was the division i can't divide 2 divided by 10 it will answer 0, i wonder why now i know. Because / (exclamation mark) was listed as Function Script to the DOS so it will read as the built in DOS script not division. And also it's different to *, %, $ &,

example:

<parsers>
<parsers id="cpp_class" displayName="C++ Class" commentExpr="((/\*.*?\*)/|(//.*?$))">
<parsers id="c_function" displayName="C source" commentExpr="((/\*.*?\*)/|(//.*?$))">
