Technical Summary & Implementation

  • Engineered a high-performance evaluation engine from scratch in C++ featuring strict mathematical operator precedence adherence and double-precision float consistency.
  • Implemented a robust Pratt parsing architecture to elegantly handle complex operator precedence, infix notations, and nested scientific functional evaluations.
  • Developed a stack-based virtual machine (VM) for execution, maximizing raw computation speeds while enabling reliable, runtime type-checking with descriptive error dispatching.
  • Built natively compiled vector operations including dot products, cross products, multi-dimensional array structures, and core trigonometric functions.
