If you want to be super God, you must be fine!Knowledge Preparation: 1. 16 binary form of the output floating point number? (with pointer output)Converts floating-point pointer-to-integer pointer to output the pointer content in 16-binary

Python standard library: built-in functions hex (x) and pythonhex This function is used to convert a hexadecimal string representation of an integer object, such as the 0x format. If the object is not an integer, define a method ___ index _ () to

This function converts a string representation of an integer object to 16, such as a format like 0x . If the object is not an integer, a method ___index__ () should be defined to return an integer. If you want to convert the result of this function

In printf: If output is in%f format, 8 bytes will be output (scanf input,%f is 4 bytes)When the parameter is in the stack if it is a float type or double directly into the stack 8 bytes, the output and subsequent output is no problemHowever, if the

Integer type (range unlimited)Decimal 1-1Binary 0b1-0b1Octal 0o1-0o1Hex 0x1-0x1Floating-point type (limited in scope but negligible)　　an indeterminate mantissa is present in the operation:0.1+0.2!=0.3Cause: Binary means that decimals can be

1. Recently doing some sqlite3 things, defined a blob type of field, want to put double-precision floating point in here, so the strange thing happened. Double precision floating point number 13.46, hex 402A EB85 1eb8 51EC, but sqlite inside data is

Identifier:Start with a letter, underscore (_), dollar sign ($)You cannot use keywordsCase sensitiveYou can divide int a = 1_0000_0000_1121 with an underscore;Data type:int defaults to decimal, octal starts with 0, Hex starts with

Int (x [, base]) converts x to an integer long (x [, base]) and converts x to a long integer float (x) convert x to a floating point complex (real [, imag]) to create a plural str (x). Convert x to a string repr (x) convert object x to expression
