Version 0.1.3

2021-04-02

• Functions now work with units.
  • max(), min(), abs(), ceil(), floor(), and round() all preserve the unit of their arguments.
  • Trig functions still only work on unitless values which is correct since angles are unitless.
  • sqrt(), cbrt(), ln(), log2(), and log10() still don't work with unit-ed values. This will be fixed in a future update but likely not soon.
• You can alias hard to type variables now.
  Ex:
  alias dx \frac{dx}{dt}
alias dt \Delta{t}

dx = 5 m/s
x = dx * dt = ?

  is equivalent to
  \frac{dx}{dt} = 5 m/s
x = \frac{dx}{dt} * \Delta{t} = ?

  

Version 0.1.2

2021-03-31 This update is really small but it improves the experience a bit so I thought I'd push it quickly.

• Fixed redundant parenthesis placement on addition and subtraction.
• Fixed a bug with unit parsing

Version 0.1.1

2021-03-30

• Added constants \pi and e
• Added mathematical functions:
  • max(a, b, c, ...): returns the maximum value of all arguments
  • min(a, b, c, ...): returns the minimum value of all arguments
  • abs(n): returns the absolute value of n
  • Trig functions: acos, acosh, asin, asinh, atan, atanh, cos, cosh, sin, sinh, tan, tanh,
    Remember to specify degrees when applicable, e.g. cos(\pi) is equivalent to cos(180 deg).
  • cbrt(n): returns the cube root of n
  • sqrt: returns the square root of n
  • ceil(n): returns the ceiling of n
  • floor(n): returns the floor of n
  • ln: returns the natural log of n
  • log10: returns the log base 10 of n
  • log2: returns the log base 2 of n
  • round: returns n rounded to the nearest integer
  Functions currently only work on values that do not have units. This should hopefully be fixed in the next update.
• Fixed unnecessary spaces appearing sometimes
• Fixed trailing zeros showing up on integers sometimes

Thanks to @Tyilo on GitHub for his work on functions and trailing zeros!
