JJ.Framework.Mathematics.Legacy 0.259.7239

JJ.Framework.Mathematics.Legacy

Miscellaneous math helpers from a 2015 code freeze. It's a legacy release for projects that still depend on it.

This legacy release supports newer and older .NET versions, has IntelliSense docs and supports code trimming and native compilation.

A newer, extended version is JJ.Framework.Mathematics but it officially only supports .NET 4.6.1 though there's a good chance it still works for later versions too; compatibility was a high priority during its development.

This legacy release contains the following features:

Maths Helper

Class extending the Math helpers from .NET with:

• Pow
  • Integer variation of the Math.Pow function.
• Log with integers
  • It will only return integers, but will prevent rounding errors such as 1000 log 10 = 2.99999999996.

Randomizer / RandomizerLegacy

• GetRandomItem TryGetRandomItem
  • Gets a random item out of a collection.
• GetInt32 / GetSingle / GetDouble
  • Return a random number out of a range.

NumberingSystems

• ToBase Converts an int to an n-base number in usually string format.
• FromBase Converts an n-based number to an int. The input is usually in string format.
• You could convert from one base to another by first calling FromBase and then ToBase.
• Several overloads to handle it differently.
• FromHex / ToHex
• ToLetterSequence / FromLetterSequence Does spread-sheet-style letter sequences. This is not the same as a base-26 numbering system. After the range A-Z is depleted, the next value is 'AA', which is equivalent to 00, so you basically start counting at 0 again, but you get 26 for free.

Release Notes

2026-04-08 | 0.253/4.5 : Legacy

• Legacy release with the following features:
• Integer-based Pow and Log, GetRandomItem and Randomizer.GetInt32, number base converter.
• 100% coverage with meaningful tests, compatibility with Code Trimming and AOT / native compilation, and a whole spread of .NET versions, and IntelliSense doc everywhere.
• Fix: Pow and Log edge-cases
• Fix: Removed dependency on JJ.Framework.Reflection.Legacy

2026-06-29 | 0.256/4.8 : RandomizerLegacy Move

• Moved RandomizerLegacy class from .Core variant of project to .Legacy project.
• Fully tested and now release as part of the .Legacy lib.
• Expanded for coherence. And ported back to 2021 legacy branch.
• (RandomizerLegacy is a 2021 version. Legacy projects contain code from 2015; Core projects code from 2025. Code from 2021 is somewhere in the middle. It made more sense to move those from .Core to .Legacy since the workflow around Legacy code is so much different than Core, that it makes more architectural sense to group them.)
