How Do I Parse Exponential Notation Numbers in C# Using Decimal.Parse?

Parsing Exponential Notation Numbers

When working with numerical data, it's common to encounter numbers represented in exponential notation, such as "1.2345E-02". However, attempting to directly parse this string using Decimal.Parse might result in an error.

To successfully parse an exponential notation number into a decimal data type, you must specify that it's a floating point number. This can be achieved by modifying the parsing style to Float using NumberStyles.Float, as seen below:

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

By specifying the Float style, the parser recognizes the exponential notation and accurately interprets the string as a decimal number. This allows you to work with and manipulate exponential values conveniently within your application.
