A simple math parser and evaluator

Usage

$ deno run ./main.ts repl
# or
$ deno run ./main.ts 5+3

TODO

• Precedence
  • The deeper an operator parser is in the callstack, the higher precedence it has
• Intersperse calls with whitespace eating
• Negative numbers
• Grouped expressions
• Builtin math funcs
  • sin
  • cos
  • abs
  • pow
• REPL
• Evaluation
• Constants
  • PI
  • TAU
• Fix left/right associativity
  • 50/2*2+10 should evaluate to 60, not 22.5
• Tests
• More operators
• Floats
• Unary operators
