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 Number from Exponential Notation but the examples won't work for me unless I specified a culture.

Solution:

double test = double.Parse("1.50E-15", CultureInfo.InvariantCulture);

If your culture uses . as the decimal separator, just double.Parse("1.50E-15") should work.

If your culture uses something else (e.g. ,) or you want to make sure your application works the same on every computer, you should use InvariantCulture:

double.Parse("1.50E-15", CultureInfo.InvariantCulture)
