Question

I have a string "3.0E-4", it is supposed to be a decimal number.

Please advise how to convert to a decimal.

Answer 1

You can use AllowExponent and AllowDecimalPoint styles combination with decimal.Parse method like;

var result = decimal.Parse("3.0E-4", 
                           NumberStyles.AllowExponent | NumberStyles.AllowDecimalPoint, 
                           CultureInfo.InvariantCulture);

Answer 2

Try this:

decimal x = Decimal.Parse("3.0E-4", NumberStyles.AllowExponent | NumberStyles.AllowDecimalPoint);

or like

decimal x = Decimal.Parse("3.0E-4", NumberStyles.Any, CultureInfo.InvariantCulture);
