|
The calculator adds all the commonly used mathematical functions including trigonometric functions, logical and relational operators. A simple text file is used to configure the calculations which are to be performed at the end of every scan. A compiler then translates the text into highly efficient code which is executed at run time. Comprehensive error messages are generated to assist in developing and debugging complex calculations.
