Crate deterministic_trigonometry

Deterministic trigonometry across architectures without using floating point arithmetic.

• Uses (i32, i32) tuples to represent fractions.
• Uses pre-baked arrays for trigonometry results.
• Deterministic across compilers and computer architectures.
• Introduces imprecision due to rounding errors.
• Most likely to be useful for games that depend on lockstep determinism.

Example

use deterministic_trigonometry::DTrig;

fn main (){

let d_trig = DTrig::initialize();

let sine_of_pi_over_three = d_trig.sine((1047,1000));

println!("The sine of 1047/1000 radians is {}/{}.", sine_of_pi_over_three.0, sine_of_pi_over_three.1);

}

Modules

initialize

This module contains the code that sets the values for the arrays from the pre-baked tables.
