Identifiying Exponential value in C#

I am integrating a library with my c# code. There is a decimal parameter i am using from the library. Parameter return usual decimal values mostly like: 0.24756400. But sometimes it returns values in Exponential format like: 0E-8.

When i try process the parameter in my code, for example when i parse it like this: 

Decimal.Parse(paymentAuth.IyziCommissionFee);)

it gives me exception

Object reference not set to an instance of an object) when the value is in Exponential format.

If i can identify the value format (number or Exponential number) i can manage it.

So how can i identify if the value is in Exponential format? Alternatively, any suggestion to manage such situation?

You don't need to identify if it is an exponent or not

If you want to parse a string that could be an exponential format into a decimal you can use the overload of the Decimal.Parse method that takes a System.Globalization.NumberStyles parameter to do this.

var result = Decimal.Parse(
              paymentAuth.IyziCommissionFee,
              System.Globalization.NumberStyles.Float
            );

This specifies that the incoming string is a float, which you can represent using the exponential format you're talking about.

You can read the MSDN docs about this overload and the NumberStyles type here :
