Why does a C# decimal keep trailing zeros, and how do I remove them?
1.10m prints "1.10" because System.Decimal stores a scale alongside its digits, and arithmetic, parsing, and JSON all preserve it. How the scale is chosen, why 1.1m == 1.10m but their strings differ, three ways to strip trailing zeros (G29, a 0.## pattern, dividing by 1.000...m) and the 1E-05 trap in G29, how to force a fixed scale, and why .NET 11's double to decimal change produces digits no trick removes. Verified on .NET 10.0.14 and .NET 11 RC3.
