using static Unity.Mathematics.mathx;return anyVector.length().clamp(0, 10).cos().sq().cube().rotate(anyQuaternion).clint().div(3.2f).rcp().mul(3.2f).sum();// Example
float3 x = new float3(1,1,1);
// here x is set before computing lengthsq()
var x = x.mult(4.2f).shuffle().set(out x).lengthsq() + x;
// we would have to write two lines instead
x = x.div(4.2f).shuffle();
x = x.lengthsq() + x;
bool4.any(); // returns true if any component is true // or-gate
bool4.all(); // returns true if all components are true // and-gate- Fast Functions

Unity.Mathematics.mathxclass (To prevent multiple using declarations) - All Methods should follow a lower case syntax (shader like syntax)
- All methods names should be as short as possible while conserving their meaning or naming convension
- Everything must be Open Source
- Credits should (if the author can be found) figure above code snipets or in the file header (if reusing existing code)
- file mames should follow this convention : mathx..
Example : mathx.interpolation.common (common methods for interpolation) or mathx.logix.floatx (float type related logic functions)
- File names for base types such as
boundsorbyte2should only have their type as a title : bounds.cs // byte2.cs
- File names for base types such as
- Every method should be static (if applicable)
- Dependencies should not exist if applicable
- Code must be rewritten and optimized for Unity.Mathematics, compatibility checked
- Unification is key : if some functions are already available in math or Unity.Mathematics.math (sometimes under another name), use them !
- Documentation should be inherited from Unity.Mathematics.math methods for direct extension method translations
