README.md

A high-precision scientific calculator with support for units, derivatives, and more.

todo: Try the web version!

Many features are missing, this is still under development.

Features

  • Extremely high precision
    • Uses a rational datatype when possible,
    • Uses a high-precision float when not.
  • Pretty printing in prompt
    • Makes expressions shorter and easier to understand
  • todo: Supports nearly all physical units
    • Accounts for units in calculations
    • Explicit conversion operator -> or to
  • todo: Variable and function definitions
  • todo: Easy history recall
  • todo: Sums and products

Reference

Operators, sorted by priority (high to low)

Operator Syntax
function application sin, cos, etc
factorial !
powers ^, **
implicit multiplication , 3(2+1), etc
square root sqrt, rt,
negation -3, -(1 + 2)
modulo (short) %
multiplication, division *, /, ×, ÷
addition, subtraction +, -
modulo (long) mod

Note that implicit multiplication has a higher priority than mulitiplication and division.
