public static string GetIEEE754Format(this double number)
        {
            return number.ToString();
        }

Is it an easy way to implement this method ? Can someone explain how to implement this function in C# code ?

IEEE 754 is not related at all to the string representation of a floating point number, but rather to the binary representation. Therefore it doesn't make sense to convert a double to string in this context.

For example if your floating type is double (as in your example), the IEEE 754 standard specifies that the 8 bytes that are required to represent it have the following structure:

1. The first bit holds the sign.
2. Next 11 bits hold the exponent (offseted by -1023 to be precise).
3. Next 52 bits hold the mantisa.

The value of such a variable is:

 (-1)^(sign) * (1.<mantisa>) * 2^(<exponent>-1023)

Altogether it's 64 bits that correspond to those 8 bytes. Any double variable has this structure already (in a system using IEEE 754, which is very common).

A similar defintion exists in the IEEE 754 standard for 32 bits float values.

In docuentation You have method to convert data types to bytes. See: https://docs.microsoft.com/en-us/dotnet/api/system.bitconverter.doubletoint64bits?view=net-6.0
