How Can I Display Decimal Values in C# with a Specific Number of Decimal Places?

Controlling Decimal Precision in C# Output

Accurate decimal representation is vital, especially in applications requiring specific formatting like financial systems. C#'s default ToString() method for decimals may show more decimal places than needed. To control this, use custom format strings within ToString().

Here's how to specify the number of decimal places:

• ToString("#.##"): Displays up to two decimal places, removing trailing zeros. For instance, 0.5m.ToString("#.##") outputs ".5".
• ToString("0.##"): Displays up to two decimal places, adding a leading zero if the value is less than 1. 0.5m.ToString("0.##") results in "0.5".
• ToString("0.00"): Always displays two decimal places, padding with zeros as needed. 0.5m.ToString("0.00") returns "0.50".

These ToString() variations offer precise control over decimal display, enhancing both accuracy and visual presentation.
