How to Parse Numbers in Exponential Notation Using Decimal.Parse()?

Parsing a Number from Exponential Notation

When attempting to parse a string expressed in exponential notation using Decimal.Parse("1.2345E-02"), you may encounter an error. This is because the default parsing method does not recognize exponential notation.

To successfully parse such a string, you need to explicitly specify that it represents a floating-point number. You can do this using the NumberStyles.Float style, as shown in the following example:

decimal d = Decimal.Parse("1.2345E-02", System.Globalization.NumberStyles.Float);

By using the NumberStyles.Float style, the Decimal.Parse method will recognize the string as a floating-point number and will successfully parse it to its decimal representation.

The above is the detailed content of How to Parse Numbers in Exponential Notation Using Decimal.Parse()?. For more information, please follow other related articles on the PHP Chinese website!
