    python binary file to hex string

    Decimal system is the most widely used number system. Binary, octal and hexadecimal number systems are closely related and we may require to convert decimal into these systems.Standard Python floating point numbers are 64 bits long, so if you use 32 bits then some accuracy could be lost.The name 'hex' comes from 'hexadecimal': a standard numerical format for representing binary data.Non-identical instances of a class normally compare as non-equal unless the class defines the that hold floating-point numbers with user-definable precision.) Numbers are created by numeric literals or as the result of built-in functions and operators.One (fragile) way to avoid that Python 2.3 interprets 0x80000000...0xffffffff (on 32-bit systems) as negative integers is to add an explicit sign: Looks good.
