Scientific notation

Add support for scientific notation

Fixes #260 @adisidev

[amishn2008]

Thank you for working on adding support for scientific notation.

src/misc/string_to_decimal_converter.cpp is an error-prone part of the software. Please add the tests for the new cases to: tests/unit/test_string_to_decimal_converter.cpp

Shifting @nihalzp comments here:
#273 (comment)

This issue arose while testing this:
#283

We use clang-format to format the C++ files. The style check is complaining that the file is not properly clang formatted. One way to solve it is to install clang-format, set clang-format as your default formatter, and running the auto-format command on your IDE.

Bumping this too. I think simply using "Format" should work as your IDE will be smart enough to detect the presence of a .clang-forrmat file and use that as the style guide for formatting. Lmk.

+ * @brief A utility class for converting string representations of numbers to
+ * decimal format.
+ *
  * This class handles various number formats including:
  * - Regular decimal numbers (e.g. "123.456", "123,456")
  * - Scientific notation (e.g. "1.23e-4", "1.23E4")
  * - Special value "NA"
- * 
+ *
  * For scientific notation:
  * - Both 'e' and 'E' are supported as exponent markers
  * - The mantissa can use either '.' or ',' as decimal separator

Error: clang-format issues detected in the following files:

Run 'clang-format -i' to fix.

The clang-format is failing. Just a simple auto format command on your editor for the file include/string_to_decimal_converter.hpp will do the trick.
