How Can I Remove Trailing Zeros from Decimal Numbers Without Losing Precision?

Efficiently Removing Trailing Zeros from Decimals: A Precision-Preserving Approach

Many datasets include decimal numbers with trailing zeros, impacting data presentation. This article demonstrates how to remove these zeros without compromising numerical accuracy.

Simply using String.Format("N0") is insufficient, as it rounds the numbers, potentially altering data integrity.

A superior method utilizes Decimal.GetBits(), accessing the decimal's underlying bit structure. Dividing the decimal by the constant 1.000000000000000000000000000000000m modifies the exponent, effectively removing superfluous trailing zeros.

This technique is easily implemented using an extension method:

<code class="language-csharp">public static decimal Normalize(this decimal value)
{
    return value / 1.000000000000000000000000000000000m;
}</code>

Applying .ToString() to the normalized decimal yields a string representation without trailing zeros, while maintaining the original numerical precision. For instance:

<code class="language-csharp">1.200m.Normalize().ToString(); // Returns "1.2"</code>
