I am using the following code to convert cm to the meter.
public static double? ConvertCmToM(double? cm)
{
return cm.Value * 0.01;
}
When I input the number 8.8 output giving as
0.08800000000000001m
But I want to stop in the index where zero adds no value in the decimal part. In this case I want to display the value as
0.088m
This is already done in major converter websites. when you type the cm to m converter on google those sites will appear. How do they do it?
I took the same sample and put in their sites and this is how they show.
> 0.088m
I cannot blindly substring the value after converting to a string as the zero part will appear in 5th or 6th element. That also handled in those sites.
This is a double data type. the letter "m" concat at the last minute. How to acehive this?

I would use decimal instead of double then:
public static decimal? ConvertCmToM(decimal? cm)
{
if(cm == null) return null;
return Decimal.Multiply(cm.Value, 0.01m);
}
static void Main()
{
Console.Write(ConvertCmToM(8.8m)); // 0.088
}
