Does Decimal.Parse() support scientific notation?

I am trying to convert such values as 1E-08 to a decimal in C# because decimals are the preffered datatype for handling funds yet I get an error upon decimal.Parse() "Input string was not in a correct format." wouldn't converting to float first and then to decimal defeat the purpose?

Are you actually trying to convert the string `1E-08` to a `decimal`? — Dave Zych, Nov 26 '12 at 19:08

Yes, converting to float would indeed defeat the purpose. The good thing is, you don't have to do that here!

You can use an overload for Parse that takes a NumberStyles specifier:

decimal d = decimal.Parse("1E-08",
     System.Globalization.NumberStyles.AllowExponent);

Of course, if you are merely specifying a hard-coded decimal, you can use the decimal literal format:

decimal d = 1E-08M;

Even though I am greatful for the explanation System.Globalization.NumberStyles.AllowExponent doesn't work – user1841964 Nov 26 '12 at 19:25

@user1841964 it is working fine for me. Prints `0,00000001` – Esailija Nov 26 '12 at 19:29

You can try with :-

 decimal x = decimal.Parse("1E-08", NumberStyles.Float);
