I’am currently upgrading a old project to the Unity.Mathematics System to Burst Compile.
I search the Mathf.PingPong Function, is there something available?
Later i will add other searches here, so if someone can’t find Functions from the old Mathf in the new Mathematics, let me know.
Thanks

There’s a few useful ported functions here (not pingpong)
//#define INCLUDEMATHCHECKS
using System;
using Unity.Mathematics;
using Unity.Sample.Core;
using UnityEngine;
// Collection of converted classic Unity (Mathf, Vector3 etc.) + some homegrown math functions using Unity.Mathematics
// These are made/converted for production and unlike a proper library they are lacking any tests, so use at your own peril!
public static class MathHelper
{
const float kEpsilonNormalSqrt = 1e-15F;
// TODO: Should likely be platform dependent, maybe a value in unity.math?
const float kEpisilon = 1.17549435E-38f;
[ConfigVar(Name = "math.show.comparison", DefaultValue = "1", Description = "Show old vs new math comparison")]
public static ConfigVar CompareMath;

such as SmoothDampnalge, Repeat, DeltaAngle, MoveTowards, LerpAngle etc etc
You can always port directly from Mathf. Either by decompiling, or you can find decompiled sources, e.g.:
// Unity C# reference source
// Copyright (c) Unity Technologies. For terms of use, see
// https://unity3d.com/legal/licenses/Unity_Reference_Only_License
using System;
using System.Threading;
using System.Runtime.CompilerServices;
using uei = UnityEngine.Internal;
using UnityEngine.Bindings;
namespace UnityEngineInternal
{
[Unity.IL2CPP.CompilerServices.Il2CppEagerStaticClassConstruction]
public partial struct MathfInternal
{
public static volatile float FloatMinNormal = 1.17549435E-38f;
public static volatile float FloatMinDenormal = Single.Epsilon;
public static bool IsFlushToZeroEnabled = (FloatMinDenormal == 0);
}

As for the PingPong method, here it is:
// PingPongs the value t, so that it is never larger than length and never smaller than 0.
public static float PingPong(float t, float length)
{
t = Repeat(t, length * 2F);
return length - Mathf.Abs(t - length);
}

Thank you that is what i searched for, i can change the Mathf.Abs function to the new Mathematics.Abs function, to get it Burst ready
