Convert numbers with exponential notation from string to double or decimal

Question

Is there a fast way to convert numbers with exponential notation (examples: \"0.5e10\" or \"-5e20\") to decimal or double?

Update: I found Parse a N

Answer 1

the Math.Round does it well, it will reder the number so that will remove, here is how to use it:

Math.Round(Double.Parse("3,55E-15"),2)
