No project description provided

calc-rs

a calculator module for Python and Rust capable of computing arbitrarily long equations and functions.

Speed Test

These tests were done using hyperfine and the speed-test.sh script in the test folder

testing python version:
Benchmark 1:  python -c "import calculator as calc; calc.solve_func(\"f(x)= 4+3x+x**2+x**3\", -1000, 1000)"
  Time (mean ± σ):      1.150 s ±  0.018 s    [User: 1.130 s, System: 0.016 s]
  Range (min … max):    1.126 s …  1.231 s    50 runs


testing rust version:
Benchmark 1:  python -c "import calculators as calc; calc.solve_func(\"f(x)= 4+3x+x^2+x^3\", -1000, 1000)"
  Time (mean ± σ):      11.8 ms ±   0.8 ms    [User: 10.6 ms, System: 3.6 ms]
  Range (min … max):    11.1 ms …  14.5 ms    25 runs

As you can see the rust version is significantly faster.

Usage

there are three functions that this libray exposes:

Function	Args	Description
solve	equasions: list(str)	takes a list of equations as strings and solves eatch one returning a list of answers.
solve_func	f: str, start: int, stop: int	solves the function, f, at all integer points between start and stop.
solve_funcs	fs: list(str), start: int, stop: int	solves a list of functions, fs, for all integer points between start and stop. returns a dictionary whose keys are function names and whose values are a tuple of a list of x values and a list of y values.

Installation

with pip:

pip install calc-rs
