This version will change the method that is used to convert the number into binary format. With this version, following features are added to this module:

• Scaling up the number to an integer, which is a more robust way to handle the conversion procedure.
• Handling the edge cases such as +Inf, -Inf, Nan, qNan, sNan, +0, -0, and denormals.
• In the output, the sign, exponent, and mantissa bits are separated with a whitespace now.
• str2hex method is renamed as hex to return the hexadecimal output.
• json format is added to get all the details of the results.

Also this version has fixed the issues:
Inaccurate results for some values - #3 (comment)
Precision issues - #2 (comment)
Wrong result - #1 (comment)

Thank you all for the support and the contributions. I hope you enjoy the new version.
